Super military empire

Chapter 242 Tungsten powder with a purity of 99.99% came out

Liu Yijiu cleaned up his thoughts and walked outside.

He hasn't left the cave for many days.Must go out to meet the sunshine.

When I arrived at the entrance of the cave, I saw Li Rui, who was still wearing military uniform, knitting a sweater on a single bench, raising his head from time to time to look inside.What she is doing here is self-evident.

Li Rui was wronged, more wronged than anyone else.

But this grievance can only be endured silently by himself, and cannot tell anyone.

Her fate is doomed, and Liu Yijiu's fate is also doomed.There are basically not a few young girls in this base. She has even decided that she must find Zheng Hao to arrange a job for her after the new year, otherwise she will get depression.

"Liu Yijiu, stop!" With a sore neck, he just raised his head to prepare for a move. When he saw Liu Yijiu who had walked to the door, he was turning around again, and suddenly ignoring the image of a lady he had maintained, shouted to him.Put the sweater, brazier and ball of thread on the stool and ran forward."Liu Yijiu, do you think it's interesting to always avoid me? These things can pass by hiding?"

"Comrade, I'm sorry, no one can enter without a certificate, please don't make us embarrassed..." The soldier on duty at the door resisted the urge to laugh in his heart.They were soldiers from the garrison battalion that had originally stayed at the base. Because the personnel had been transferred in half, the guards at the entrance of the base have changed from four to two.

"Don't touch me, I know the rules, I won't go in!" Seeing Liu Yijiu disappearing in front of him, Li Rui stamped his feet with anger.

In the end, he had no choice but to pack up his things and go back.She knew why Liu Yijiu had to avoid her, but she could not decide this matter.

Life is easy, and she hopes to have a good talk with Liu Yijiu.It is destined to be such a destiny. If you do not accept it, you can only find yourself in this way.Li Rui even regretted that he agreed to let her enter such a unit back then.

Li Rui stayed outside. Liu Yijiu really didn’t want to meet her. Cao Zhijiang and the others were still discussing the improvement of the 336 rocket launcher. He didn’t bother to listen to their design plans. If everything was his cheating, he told them. In the end, they will be like those talents cultivated by the Republic since the 1980s, everything is imitated design, and then independently developed abilities and thinking.In the end, there was really no alternative but to go to the second district.

It is also very interesting to discuss various material element ratios and conduct some experiments with Jia Yiming when it is okay.

He has memorized a lot of material formulas and most of the production processes, but he does not know how these processes can produce more effective results. He is not interested in these things.

Tungsten, which is a very widely used metal element, is even more important than steel in some aspects.

Especially the military industry.

In the past, tungsten powder was produced in China with tungstic acid or yellow oxide. The effect of this process is not very good, the cost is high, and the quality is low.In the early 1960s, foreign countries began to vigorously study the preparation of tungsten powder from blue tungsten oxide.

In this regard, the relationship between the two parties was broken because the Soviet experts had not completed the final production equipment design and other technology transfer.

The 754 factory has blue tungsten production technology. These are the incomplete technologies obtained by domestic experts in some burned and semi-disabled materials left by Soviet experts.Naturally, you can imagine how much the effect can be.

Domestic tungsten powder production still uses tungstic acid and yellow tungsten oxide instead of blue tungsten.

"Why are you free today?" Jia Yiming was a little surprised when Liu Yijiu came over.

This young man is very talented in all aspects, and sometimes it is very shocking to bring up something unconsciously.

Can give people a lot of inspiration.

Although he himself does not admit it, this is the fact.

"I was blocked by Li Rui? That girl is not bad." Jia Yiming originally hoped that his daughter could think about it with Liu Yijiu, but Luohua deliberately flowed ruthlessly, but now these days, his parents are not happy.Especially now that Liu Yijiu showed that which woman married him is really not happy.

Liu Yijiu rolled his eyes.

"How is the production process of blue tungsten? Does the refined purity meet the requirements we want?" Liu Yijiu didn't want to talk about it anymore.

The blue tungsten production process is the most important.The manufacture of various gun barrels and barrels is very necessary for this thing, not to mention that the main component is the hard alloy knife of this thing.If they want to get some advanced equipment, only materials are not enough.

Hard-to-machine materials such as titanium alloys, new gun steels, and high-temperature alloys must be processed with better tools.

This is how the Americans came up with advanced materials, like titanium alloys, and the processing cost exceeded their imagination...

In the end, they all cried.

The Soviet Union is even more so. Because these titanium alloys cannot be processed, the MiG-25p can only choose to use nickel-based alloys that are three times heavier than aviation aluminum and twice as heavy as titanium alloys to make the aircraft shell. This allows the MiG-25p to achieve speeds exceeding Mach 3.But this time is very short.

The blackbirds in the United States are also for this reason.

With materials, there must be matching processing technology!

Of course, the premise is that materials must be available.

"This purity has been achieved during the experiment, but no solution has been found for the particle size problem you requested. Here is a pure tungsten powder that has been tested using two methods under a 1000x microscope. Your kid is also an expert in this area. If you don't do it yourself, you have to let me..." Jia Yiming motioned to Liu Yijiu to look at the things under the microscope.

Upon seeing this problem, Liu Yijiu suddenly became depressed again.

If there is an electron microscope, it would be great to directly photograph these fiber structures!

That way, the horizontal comparison will be more obvious.

"How much is the particle size measured? We should build an electronic probe scanner, and we also need a laser particle size analyzer, otherwise, many experiments can't go on..." Liu Yijiu had a headache.

"Don't expect it. This kind of thing is the most top-notch equipment in the world, and it will not be provided to our country at all. The domestic optoelectronic research institute wants to get it, but there is no way, how to solve these problems and directions. I don't know where it is. The laser particle size analyzer requires a microcomputer. The Chinese Academy of Sciences has a Soviet Union, which is long gone..." Jia Yiming sighed.

Electronic probe scanners and laser particle size analyzers are not the top materials experts in China, and they have not even heard of them.

Liu Yijiu took out his work notes from his pocket and filled in the names of the two devices at the back.This thing is that in the early 21st century, the Republic had to import from abroad, not to mention the high price, even if you spend money, you can’t buy it, and you have to suffer a lot of blindness. It can only be obtained through some large international smuggling groups. This one.

"Don't worry, someone will provide it to us." Liu Yijiu said confidently.

"Using the method you said, the ammonium paratungstate is in the single-tube reduction furnace. The air is drained through nitrogen first, and then a constant flow of hydrogen is added at 2.6 cubic meters per hour. The first stage is heated to 730°C, and the second stage to 800° c. The third stage is 850°C and kept for 30 minutes. The final purity has been tested and it can reach 99.99%... The purity problem can be infinitely close to 100% through the blue tungsten preparation process again, but this particle size problem..." Solved, but the granularity problem has become a problem again.

"Have you ever tried to grind Wufeng?" Liu Yijiu asked suddenly.

"Grinding? Necessary" Jia Yiming jumped up immediately.

Is this a joke?

How hard is the tungsten powder?

"Maybe you can try it, just like grinding, maybe we can get a finer powder..." After Liu Yijiu finished speaking, he turned and left.

If he doesn't leave, Jia Yiming will definitely ask how to grind and what to grind.

Liu Yijiu knows a fart!

He knew that there was such a craft, and he couldn't understand everything, right?

"Don't go, you haven't said how to grind it..." Jia Yiming was as expected by Liu Yijiu. When he returned to God, Liu Yijiu had already arrived at the door of the laboratory. Hearing his words, he suddenly Quicken the pace.

Since the pure tungsten powder has been produced, it is only a matter of the thickness of the powder. When the powder is studied more finely, it can be verified in this aspect. Perhaps, this production process can be used to scare the Yankees and let them Give something more.

The Yankee's production process should not have reached the level of the 21st century!

Without reminding them, it is estimated that they will never think of this problem in their entire lives.This is an unexpected process, mainly used in ultra-fine powder metallurgy.It is not yet in the 1980s, and the American emperor should be struggling to pursue this.

The tungsten core rear wing stable shelling armor-piercing projectile can be used, and the new gun steel can be used.

Cannon-steel, it is better to grow materials without rare earths for the American Emperor.Later, when they are about to get it out, they will continue to cheat the Americans. How they cheated the Republic back then must be cheated back.

The main work of the Ninth District is to study the 500 kilograms of cloud explosive bombs dropped by aerial means. Individual soldiers are also getting them, and even they want to get ordinary shells. This has been prevented by Liu Yijiu. The Republic reserves I don’t know how many 10,000 rounds of conventional artillery shells there are. If you use these things, the conventional artillery shells will be useless.

Can't the artillery shoot cloud explosive bombs when they are shooting?

This is simply too prodigal.

For Liu Yijiu's arrival, the technical and management personnel of the entire nine districts are now extremely welcome!
