Chapter 275 Reserve Two First Prizes
The comrades from the Propaganda Department finished their work quickly and went back to write the manuscript.

Chief Engineer Chen revised Yu Yuncheng's report as quickly as possible and signed it, then mobilized many comrades from the confidential office and the Propaganda Department to copy the report on single crystal furnaces and single crystal silicon.

You take a few pages, I take a few pages, it will be done very quickly. But some people may worry, what if the handwriting is different?
Many comrades engaged in propaganda these days have a unique skill called printing.

What it means is that if you write according to the printed font, as long as you are an expert, the words written by different people may not look exactly the same, but at least they will be very similar.

So in the afternoon, the three single crystal silicon rods, along with the report, were sent to the Chinese Academy of Sciences and two ministries under the escort of the factory militia.

The 17th Ministry of Machine Building received reports on tungsten-molybdenum alloys in addition to single crystal silicon rods.

The first glance at it made the leader's eyes go straight. The melting point is 2600°C? At the same time, it has good processing performance and can be forged, rolled and machined?
There are many metals with high melting points. For example, tungsten, one of the components of tungsten-molybdenum alloy, has a melting point of over 3400°C. However, its processing performance is not very good. No matter whether it is rolled, forged or turned, it is rare to find one that can process it.

It is difficult to process, which greatly limits the application of tungsten's high-temperature performance. However, the thing Gao Zhendong made can carry out these processes very conveniently, which is different. It can be used in many places.

If only its density could be close to that of steel, no, copper, then it could be used in more places.

Thinking of this, the leader couldn't help but scold himself. What good thing was he thinking? He wanted everything, right? Haha.

Of course, good processing performance often means another problem: not so hard, but it doesn’t matter. What is needed here is high temperature performance, not hardness.

This is one of the reasons why tungsten-molybdenum alloy is not used in armor. In addition to being too heavy, its specific gravity is about 18, which is really incomparable to the 7.8 of steel alloys. At the same time, its hardness has no advantage over high-hardness armor steel.

The hardness of tungsten-molybdenum alloy is about 60-70HRC. Taking the 592 nickel-free alloy armor steel made by Gao Zhendong as an example, the hardness is 370~480HB. A conversion needs to be made between HRC and HB.

HRC=0.098×HB+32.25.

If you do the math, you'll find that the hardness of tungsten-molybdenum alloy is even lower than that of 592 armor steel.

But this does not affect the use of tungsten-molybdenum alloy. We not only need a steel torrent, we also need an industrial tide and aerospace.

After reading the report on tungsten-molybdenum alloy from beginning to end, the leader was very excited. This is different from materials like 592 and 593 which have special uses and are basically limited to military industry. This is something that can be used in any industry as long as the demand matches.

He immediately called the confidentiality department and handed them the tungsten-molybdenum alloy material: "You desensitize this material, and then immediately inform the Ministry of Machinery, the Ministry of Science and Industry, and other relevant ministries and commissions."

The comrade from the confidentiality department took immediate action, and then he read another report with a satisfied mood.

Single crystal furnace and silicon single crystal.

As soon as he read the beginning, he stood up, rushed to the door, and asked Secretary Sun: "Xiao Sun, is there a sample with this report?"

Secretary Sun said: "Yes, there is a sample."

"Take me to see it right away. Oh, and call the chief engineer right away!"

At this time, he no longer cared about "calling" and "inviting", so he had to inconvenience the chief engineer.

Rushing to the warehouse where the silicon single crystal rods were stored, the leader was dazzled by the sight of the silicon single crystals in front of him. This was the main business of the 59th Ministry of Machine Building, and to him, it was more fascinating than DJS- and lasers.

Haha, Gao Zhendong has been researching for so long, and he has finally made a treasure for the 59th Ministry of Machinery. Although the X series is also groundbreaking, it is all groundbreaking in specific materials, and overall it has not jumped out of the framework of "iron-based alloys".

Silicon single crystals can be said to have pioneered the silicon industry. From then on, all people engaged in silicon-related industries cannot avoid it. Especially the 12th Ministry of Machine Building. Thinking of this, the leader of the 17th Ministry of Machine Building laughed out loud.

After a while, the chief engineer of the 17th Ministry of Machine Building also rushed here. After hearing what his leader said, he was overjoyed. As the head of the technical aspects of the 17th Ministry of Machine Building, he knew better than his leader what this thing represented.

He rudely "grabbed" the report on silicon single crystals from his leader's hands, took off his glasses, tilted his head, put the report at a certain distance from his eyes, and squinted his eyes to read it carefully.

Reading glasses are like this. If you use them too close, they won't work. This is how many elderly people look at things.

The chief engineer of the department watched as his expression gradually became agitated.

This means that the source of semiconductor materials that has been a problem in the past has been completely solved. Not to mention silicon, the earliest germanium tubes used germanium extracted from furnace ash. Except for special requirements, silicon tubes are inferior to germanium tubes, but the characteristics of silicon tubes are superior in all aspects. The biggest obstacle to the application of silicon tubes lies in the raw materials.

He knew that the 1761 Institute had produced a silicon single crystal with 4 nines last year, but it was still an order of magnitude short of being used in the electronics industry. And as far as he knew, the 9 nines route was successful, but the technology was still far from mature.

Because of this, he was often laughed at by the chief engineer of the 12th Ministry of Machinery. The most common sentence he said was: "We can design this thing, but the 17th Ministry of Machinery has no materials for us, so we can't make it either."

Now the Third Steel Rolling Mill has produced a silicon single crystal with a quality better than 5 9s. I wonder what excuses he can find. Hahahaha, I will squat at his door every day to see what he can produce. Even if this was produced by accident, it doesn't matter. If it can be produced, it means that the technical route is correct and can work. At most, we can research and improve it to increase the yield rate.

Anyone who works in technology knows that there is a huge difference between "0" and "1".

If the four nines do not warrant in-depth research and process improvement and optimization, then the five nines single crystals are very necessary.

After looking at all the parameters of the silicon single crystal one by one, the chief engineer smiled and said, "Leader, it's only April, and the Third Rolling Mill has already reserved a place for this year's Liehuo Technology First Prize."

The leader smiled and pointed at the materials in his hand: "Don't get excited, look back, there may be more than one."

The chief engineer looked confused. Is there anything else?

He continued to flip backwards, and suddenly a look of ecstasy appeared on his face.

What did I see? "Universal single crystal furnace"?
The chief engineer of the department tried hard to hold back his joy and curse. It was not a typo, nor was it a wrong word. Instead, these two seemingly unrelated words, when combined together, really represented his current mood.

Single crystal furnace, as the name suggests, this is a standard and mass-producible equipment for mass production of silicon single crystals.

It's hard to read, but it's the truth.

It can be used for mass production of silicon single crystals, and the equipment itself is mature and has the conditions for mass production.

The mood of the chief engineer is like the tide, one wave higher than the other. There are silicon single crystals with 5 9s~~~~~~Silicon single crystals can be mass-produced~~~~~~The equipment for mass-producing silicon single crystals can also be mass-produced~~~~~~
He was just thinking that if this silicon single crystal was an accidental or experimental result, then he must support the third rolling mill to develop it and make it mature.

But now I find that it is no longer necessary, as others have already solved it, and solved it very thoroughly.

He turned around and said to the leader of the 17th Ministry of Machinery, "Leader, you are right. Here are two first-class Liehuo Technology Awards. There is no doubt about it."

The leader laughed and said, "You are wrong. We should look at the problem from a development perspective. Maybe by the end of the year, we can only get the second prize."

The chief engineer didn't care about the leader's joke at all: "I don't believe it! This is the first prize. We should talk about development and objectivity. We will notify the 12th Ministry of Machinery immediately. I want to see what their chief engineer will think when he sees this. Haha, he has no excuse this time!"

The leader smiled and shook his head: "No need to notify them, the Third Rolling Mill has already been notified, and a silicon single crystal has been sent to them for testing, not only the 12th Ministry of Machinery, but also the Chinese Academy of Sciences."

The chief engineer was stunned: "They are very thoughtful. The National Academy of Sciences will do the final appraisal, the 12th Ministry of Machinery will do the application appraisal, and we will do the project appraisal, haha."

Then he suddenly realized: "They sent three at a time? This means they are fully capable of mass production. Good news, very good news, hahahaha."

The leader smiled and said, "Not only that, they have even tried things other than silicon single crystals. They have also successfully pulled alumina crystals. This shows that they are confident when they say that this furnace is a 'universal single crystal furnace'."

The chief engineer smiled at his leader and said, "It seems that the ministry has decided to fully support Comrade Gao Zhendong of the Third Rolling Mill, while not placing any restrictions on him. This is the right move. You have pushed forward this matter with all your strength, and Gao Zhendong has lived up to your expectations."

Upon hearing this, the leader laughed triumphantly. He was willing to wear this compliment and felt very comfortable wearing it.

The Seventeenth Ministry of Machine Building was excited, and the Twelfth Ministry of Machine Building was also in an uproar.

When the leader of the 12th Ministry of Machinery received the news, he looked at the secretary who came to report with a look of astonishment: "What did you say? The Third Steel Rolling Mill of the 17th Ministry of Machinery sent a silicon single crystal?"

As it was reported by a subordinate unit of other ministries and it was obviously very important, it must have been reported to him.

These days, nothing is unimportant when it comes to materials.

What's more, as for the Third Steel Rolling Plant and Gao Zhendong, needless to say, just report to the top leader.

So the news reached him immediately.

He remembered that Gao Zhendong mentioned this matter at a meeting at the beginning of the year. He was leading Comrade Yu Yuncheng from the 1761 Institute to pull silicon single crystals that met the needs of the electronics industry.

But he never expected that the product would come out in just a few months.

He is the head of the 12th Ministry of Machine Building, and he knows very well the uses of silicon single crystals and the difficulty of making high-purity silicon single crystals.
