Chapter 491 Done!

In the laboratory, Xu Chuan personally manipulated the equipment to prepare improved superconducting materials.

He had not done experiments in person for a long time, and he was more likely to drive the development of materials by solving theoretical problems.

However, the muscle memory was there. When he entered the laboratory, the familiar feeling of various equipment and instruments quickly emerged in his mind.

Through rubber gloves, Xu Chuan skillfully manipulated the micro-manipulator to transport the film that had completed the guided growth to the inert atmosphere protection furnace.

Here, this piece of film that has completed the growth will be protected by inert gas and heat treated at a temperature of 860℃-900℃ to generate the final improved superconducting material.

After completing this step, Xu Chuan took off his gloves and breathed a sigh of relief.

At this point, the entire experimental process has basically been completed.

Just wait quietly for the inert atmosphere protection furnace to complete the final heat treatment.

The rest is to test the prepared materials.

"Academician Xu, do you want to take a rest? I'll watch here."

In the laboratory, the assistant researcher looked at Xu Chuan, who was full of fatigue on his face, and asked.

How should I put it? Experiments are sometimes quite easy, but most of the time, they are very physically demanding.

Although doing experiments in the laboratory does not require moving large devices or heavy objects, precise experiments, especially material research and development, often require researchers to concentrate their attention.

After all, in the entire experimental process, once there is an error or mistake, the entire experiment is basically scrapped and can only be started all over again.

Hearing this, Xu Chuan glanced at the inert atmosphere protection furnace that had just started working and nodded.

If it were normal, he would not have exhausted himself.

But before doing the experiment today, he had been working for two or three days in a row. He had not had time to adjust himself, and he hurried to the laboratory, so his energy was naturally not that sufficient.

After handing over the rest of the work to his assistant, Xu Chuan returned to his office and leaned on the sofa to take a nap.

The reason why he rushed to complete the experiment today was mainly because tomorrow was a report meeting on the unified framework theory of strongly correlated electronic systems.

Considering the report meeting and the report meeting on large particle collisions that followed the report meeting, Xu Chuan was anxious to bring up the material experiment today.

Today, the material will be made, and a superconductivity test will be conducted first to see whether the prepared improved superconducting material has the same strong magnetic field strength as in the simulation experiment.

If yes, the rest of the test can be handed over to others, and the overall test results will be almost out after he finishes the report meeting.

If not, the Chuanhai Materials Research Institute can also analyze the overall situation of the experiment and find out the problem during his report meeting.

Otherwise, it will take several days to do it after the report meeting.

Perhaps for other researchers or scholars, a few days is not a big deal, but for Xu Chuan, it is best not to waste time.

After setting an alarm, Xu Chuan leaned on the sofa and closed his eyes for a nap for about 40 minutes.

The time is not long, but it is enough to greatly relieve his fatigue.

After all, he is young and his body can bear it.

Reaching out to get his phone from the coffee table, he turned off the alarm, got up and stretched before returning to the laboratory.

In the laboratory, the preparation of the improved superconducting material had just been completed, and pieces of silver-gray film were being transferred to glassware by assistant researchers.

Fan Pengyue, who had finished his work and rushed over to supervise, turned his head and looked at it after hearing the noise: "Why don't you take a break?"

Xu Chuan smiled and said, "That's enough. What's the result?"

The assistant researcher who followed him throughout the research and assistance quickly reported: "The improved superconducting materials prepared by visual observation are quite perfect in shape, without tearing, wrinkles, curling, etc. The specific performance needs to be determined after testing."

Xu Chuan nodded, walked forward, put on gloves, picked up a glassware, took out the improved superconducting material film from it, and observed it carefully.

The film, which was less than the size of a child's palm, was clamped between his fingers, and there was a little quasi-metallic luster on the surface.

This is a feature that high-temperature copper-carbon-silver composite superconducting materials do not have. High-temperature copper-carbon-silver composite superconducting materials are ceramic materials. Although they also appear silver-gray in the eyes, they are matte and do not have this metallic luster.

It may be that after the experimental improvement, the Cu atoms in the excessive Cu nanoparticles are doped into the holes, and the magnetic traps generated change the characteristics of the raw materials, making them reflective like quasi-metals or a small amount of metals.

After carefully observing the appearance, Xu Chuan pinched the two sharp corners with his hands and slowly applied pressure.

The film in the fingers is not very thick, and it is only the thickness of an adult man's fingernail. When his fingers applied pressure, the silver-gray film actually had some slight deformation, and the whole had a slight arc.

Noticing this, Xu Chuan's pupils condensed slightly.

This is also a feature that high-temperature copper-carbon-silver composite superconducting materials do not have.

After all, the nature of ceramic materials generally has almost no toughness. Later, he also added a little toughness to it through research with Academician Zhang Pingxiang.

And now the original material in hand, which has not been toughened by whiskers, obviously has some original toughness.

After thinking for a while, Xu Chuan wanted to see the limit of this improved superconducting material, so he found a container and continued to apply pressure slowly inside.

As the force increased, the arc of deformation began to increase, but not long after, accompanied by a crisp "snap" sound, the film pinched in the fingers burst open, and several pieces of fragments flew out and fell into the glass container.

"It has toughness, but it is far inferior to the superconducting material toughened by whiskers (fibers). It is estimated that it can achieve an arc deformation of about 7-8 degrees under pressure, and the impact toughness should be between 8-10."

Looking at the material shattered in the glass container, Xu Chuan made a simple calculation.

Although the values ​​are not high, as an unexpected gain, it is still very surprising.

After all, in terms of the physical properties of high-temperature copper-carbon-silver composite superconducting materials, the toughness value is very low, even if a small amount of improvement is obtained, it is enough to optimize a lot.

If it is combined with whisker toughening technology, I believe its performance will be even higher.

In the laboratory, Xu Chuan damaged a piece of improved superconducting material film as soon as he came up, and everyone just took a look and continued to be busy, preparing for the relevant superconductivity test.

As a big boss, you can play as you like.

Testing superconducting materials is not very difficult, and it can be done through equipment such as cryostat and Dewar liquid nitrogen container.

In particular, there is a complete superconducting electromagnetic testing system in the Chuanhai Materials Research Institute, and it is enough to just put the material in.

Xu Chuan did not test it himself, he was waiting on the side.

For the current Chuanhai Materials Research Institute, this kind of work can be said to be a test step that cannot be any smaller.

Not to say that everyone can do it, but researchers in the Superconducting Materials Research Laboratory, even a graduate student in internship, can do it.

Compared with the cumbersomeness of the critical magnetic field test, the critical temperature test data is the first to be made.

"The results of the first test of Tc critical temperature have come out, and the current temperature is 127.3K!"

In the laboratory, the assistant researcher in charge of the test quickly reported after observing the cliff-like drop in the curve.

Hearing this, Xu Chuan, who had been waiting on the side, leaned over and looked at the computer screen.

The huge display screen was divided into four parts according to the XY axis, showing different data respectively.

The data of the main performance of superconducting materials such as resistance information value, temperature control system value, magnetic field index value, AC magnetic susceptibility, etc. were all displayed.

In the resistance area, the originally smooth curve has now fallen to the bottom.

In the temperature control system value area, the huge number paused at 127.3K, and the bright red indicated the critical transition point.

127.3K, -145.85℃!

This number happened to be in the simulation result of the simulation experiment, which can be said to perfectly confirm the theory.

"It's done!"

Looking at the data on the screen, Xu Chuan clenched his fists and almost cheered!

Although the data of the magnetic field test has not come out yet, the change in critical temperature has told him the answer he wanted.

After quickly making way and signaling others to continue working, Xu Chuan sat in the laboratory and continued to wait.

The key now is no longer on the critical temperature, and the final indicator still needs to look at the critical magnetic field!

After waiting patiently for more than two hours, the first round of superconductivity tests was finally completed.

The test results were printed out and sent to him immediately.

Xu Chuan turned directly to the superconducting performance.

[Critical temperature (Tc): 127.3K]

[Critical magnetic field (Hc): At 127.3K, the critical Hc is 40.76T, and the maximum can reach 46.68T. ]

[Critical current (Ic): 52 at 43T]

[Critical current density (Jc): ]

Looking at the preliminary test results in his hand, he grinned.

This value is theoretically enough!

Not only miniaturized controlled nuclear fusion and aerospace engines, but also large-scale particle colliders that he had not considered before.

With the support of this new material, the collision energy level may be able to increase by more than half an order of magnitude on the original basis!

This will bring new science to the physics community and even the whole world!
