This furnace can withstand up to 100 standard atmospheric pressure. It can be pressurized by filling inert gas, and can release the internal gas for decompression. This is intelligently controlled. After setting it on the computer, it can basically maintain the set value. under pressure.

Soon, things were settled and everything else was ready, and they began to prepare for synthesis.

"Start adding reactants."

In the laboratory, facing the fairly complicated reactor in front of him, Lin Xiao gave an order.

The interns and assistant researchers next to them immediately acted and added the iron-based reactants and cuprate reactants that had been processed. These reactants are very pure, and the impurities in them can basically be ignored. Not to the extent of silicon wafers.

Soon, "All joined!"

"Start the reactor." Lin Xiao said again: "The temperature is set at 1200 degrees Celsius."

"The reactor has started! Start heating!"

On the other side, Zhao Sheng, who was sitting in front of the computer, also asked: "Director Lin, what atmospheric pressure should we set?"

Lin Xiao said directly: "24."

"OK."

Zhao Sheng nodded, although he wondered why Lin Xiao directly reported a number with odds and wholes, but he didn't think too much about it, and directly completed the settings on the computer.

With the sound of gas filling inside, the current air pressure is displayed on the gauge of the air pressure sensor: 24.2.

The reaction begins here.

Everyone in the laboratory had an expression of expectation on their faces, waiting for the final shape of this thing.

As time goes by, the expected reaction time is up, and then the pressure will be reduced until the interior returns to a safe value, and then it will start to be released, and then the molten liquid inside will be poured into the mold, and it will wait for cooling and forming.

They did not prepare much this time, and the final molding volume was only about 100cm^3, with a total of 10 molds, that is, ten strips with a cross-sectional area of 1cm^2 and a length of 10cm.

Seeing these ten dark-looking products, everyone present showed excitement.

The surface color of the products they obtained before was not pure black, but a kind of silvery black, but now, such a color undoubtedly shows that this thing is already a brand new object!

"Okay!" Zhao Sheng suddenly became excited. From this point of view, it has been successful!

So he didn't intend to analyze whether the internal structure of this thing was the same as they originally wanted, but said directly: "Go get liquid nitrogen and see if it can meet the requirements of high-temperature superconductivity! By the way See if this thing can be bent! How tough is it!"

"Okay!" Several assistant researchers responded immediately.

Then two people ran to get liquid nitrogen, while the other person reached out and picked up one of them, and broke it hard, and it was able to bend!

And it seems that the toughness is particularly good, completely inheriting the toughness of the original iron-based material!

"it is good!"

Zhao Sheng immediately looked at Lin Xiao next to him, with excitement on his face, "It's bent! It's really bent!"

And Lin Xiao opened his mouth. He wanted to talk about the inspection later. After all, maybe they really succeeded, but considering the importance of room temperature superconductors, maybe we can wait?

But looking at Zhao Sheng's excited look, he didn't know what to say.

In the end, he still shook his head, forget it, let them all be happy, anyway, they all signed the non-disclosure agreement.

So he smiled and said, "Yes, it's bent."

Chapter 333 All technologies will be eclipsed!

If it is bent, it means that this thing can be used as a wire.

He watched the originally straight black columnar object bend with force, and it would be a lie to say that Zhao Sheng was not excited.

After all, he was "tricked" by Lin Xiao to come up with this high-temperature superconductor that can be bent.

Among the high-temperature superconductors discovered in the current scientific community, that is, superconductors with a critical superconducting temperature above 77K, they are basically copper oxides, which can also be called cuprates, and these things are relatively brittle and have poor toughness. .

If the thing they built today can really bend, hey, among other things, it can make a lot of money.

Oh, this thing belongs to Lin Xiao, and if he really makes money, it has nothing to do with him.

Thinking of this, Zhao Sheng immediately lost his mind. Of course, he became happy again in his heart. Even if making money has nothing to do with him, he can get some related awards if he doesn't talk about it in the future.

Just for the National Natural Science Award, the first prize must be won.

Of course, the premise is that the superconducting critical temperature of this thing has really reached above 77K.

As soon as I thought of this, I saw the two people who had gone to get liquid nitrogen back and shouted: "Liquid nitrogen is here!"

"Okay, let's do the experiment!"

Zhao Sheng couldn't wait any longer, then turned his head to look at Lin Xiao again, and said, "I said, why aren't you excited at all?"

"Uh……"

Lin Xiao barely showed a slightly excited expression on his face.

It’s just that it was a bit too reluctant, so Zhao Sheng couldn’t help but rolled his eyes: “Forget it, I don’t ask you, I guess you don’t care about this kind of high-temperature superconductor, unless it’s a room-temperature superconductor that can excite you?”

Lin Xiao touched his nose, probably?

After all, after witnessing this room-temperature superconductor before, all the excitement he should have done has already been exhausted.

I just don't know what kind of expressions these people will have on their faces when they watch the temperature gradually return to normal temperature, and this thing that can still maintain a superconducting state.

He suddenly had some expectations.

So soon, the test device was completed, which is actually not complicated. Anyway, it is just a temperature sensor, which is directly attached to one of the black solids, and then tested by using the Meissner effect. This is the easiest way.

Afterwards, they poured liquid nitrogen into it, and immediately, the number on the indicator meter connected to the sensor began to drop rapidly, reaching about 77K.

Then, put a small magnet on it, and suddenly, the small magnet floated up.

Such a miraculous scene, in ancient times, was at least a celestial art.

"it is good!"

Seeing this scene, Zhao Sheng immediately shouted, and then clapped his hands.

The others immediately applauded.

This thing really meets the requirements of high-temperature superconductors!

This is undoubtedly an extremely exciting thing for them.

why?

Because liquid nitrogen is cheap!

The price of liquid helium is about 200 yuan a liter, while the price of liquid nitrogen can be as low as 6 or 7 yuan a liter.

After all, helium is a rare gas, but nitrogen can be found everywhere. You must know that 78% of the earth's air is nitrogen!

So the price of preparing nitrogen is very cheap.

Since the brand-new superconductor they created can be bent, it obviously has the value of large-scale use, such as superconducting maglev trains. In fact, the maglev trains in Shanghai use yttrium-barium-copper-oxide superconductors.

In addition to this point, this thing can also be used for power generation, that is, superconducting power generation. YBCO can be used to arrange the tracks of maglev trains because the tracks are very long and do not need to be very curved, but if it is for power generation , because it needs to be wound into a coil, the very brittle yttrium barium copper oxide obviously cannot be used, and their new superconductor can play a role.

Or, it can even be used for superconducting power transmission. Of course, it is only used in areas with high power consumption. Using the lossless nature of superconducting power transmission can greatly reduce the power load.

and also……

Zhao Sheng and the others thought more and more, and even thought of superconducting electromagnetic guns.

And Lin Xiao knew what these people were thinking when he saw their expressions as if they were in a reverie.

He shook his head, still too young.

In this way, until a period of time passed, all the liquid nitrogen poured out volatilized, and the temperature of this new type of superconductor also began to rise.

77K, 80K, 85K...

Suddenly, someone noticed the gradually rising temperature, and immediately exclaimed: "90K!"

Everyone looked over immediately, all showing surprised expressions.

The temperature has risen to 90K!

And the Meissner effect still exists, the small magnet is still floating on it, and it is constantly rolling.

"Damn! How is this possible?!"

Seeing this scene, Zhao Sheng opened his mouth wide. He has reached 90K, and he can still maintain a superconducting state?

Then he couldn't help looking at Lin Xiao, and said, "Director Lin, you have created another history!"

Lin Xiao shrugged, looking indifferent.

And seeing him like this, Zhao Sheng was even more puzzled, it was all like this, why didn't Lin Xiao feel excited at all?

However, at this time, someone next to him exclaimed: "100K!"

Zhao Sheng's eyes widened immediately, and he immediately turned his head to look at the indicator. The temperature had indeed reached 100K, but...the Meissner effect still exists!

This means that the long black thing is still superconducting!

He turned his head to look at Lin Xiao again, and couldn't help exclaiming again: "Lin Xiao, what's going on?"

Lin Xiao spread his hands, "Don't ask me, just keep reading."

Zhao Sheng quickly looked again, and the temperature was still rising!

110K...120K...

Zhao Sheng was even more shocked, and turned his head to look at Lin Xiao in an instant: "This time I want to say, you have created a miracle!"

Lin Xiao shrugged + spread his hands.

140K.

"You... well, you have created another miracle."

Lin Xiao waved his hand.

150K.

"You created...created...created a myth!"
