Chapter 490: The hope of miniaturized controllable nuclear fusion and aerospace engines(2/2)

After all, after he developed this material in his previous life, he must have gone through the past tests and verifications many times, but he never found that it had such properties.

It can only be said that it is not known whether this additional change will significantly affect the original superconducting properties.

As for the impact, there definitely is.

After all, the properties of the material have changed.

However, overall, most of the changed areas are non-superconducting parts, which should not cause it to fall directly out of the field of superconducting materials.

After all, it is extremely difficult to synthesize an absolutely pure superconductor, which will contain phases other than the required superconducting phase.

For example, the superconducting phase in copper oxide-based yttrium barium copper oxide is mainly the yttrium barium copper oxide 123 phase, but there is also the non-superconducting 211 phase. The superconducting phase in BSCCO is the 2223 phase and the 2212 phase. The critical temperatures of these two phases are

Still different.

The same goes for high-temperature copper-carbon-silver composite superconducting materials. Its main superconductor is composed of a copper-carbon-silver-based composite structure, which is its superconducting phase. In addition to the superconducting phase, there are also copper-carbon-silver materials.

Various other composite structures.

These composite structures are non-superconducting, and it is these non-superconducting phases that are changed through the model.

Using the generation of magnetic traps, combined with the original superconducting phase, to further enhance the critical magnetic field is an academic discourse.

To put it simply, it is to further dope the composite material on the composite material to continue to improve its performance.

To put it bluntly, this is what it does by using the characteristics of Cu atoms to form a magnetic trap on the non-superconducting phase.

Thinking about it, Xu Chuan continued to read through the simulation experiment results in his hands.

After completing the optimization of the material, NTU's supercomputing center calculated the superconducting properties of the optimized superconductor through first-principles calculations and material calculation models.

The data for each item is listed in the table.

This chapter is not finished yet, please click on the next page to continue reading the exciting content! Hardness, toughness, phase purity, phase ratio, hardness, plasticity and other conventional properties were the first to catch his eye.

Regarding the common properties of these materials, Xu Chuan just glanced briefly, and his eyes fell on the superconducting properties behind them.

[Simulated critical temperature (Tc): 121.6-134.3K]

[Simulated critical magnetic field (Hc): At 152K, Hc can reach 37.4T-42.7TT, and at 77K, Hc can reach the maximum value of 47.268T. ]

[Simulated critical current (Ic): It is estimated to reach 5100A/mm2 at 40T.]

【Critical current density (Jc):......】

[Thermal conductivity: 591.3W/m·k]

Three critical data appeared in Xu Chuan's eyes.

The critical temperature has indeed been reduced, from the original 152K to the simulated 121.6K, but this impact is not significant and is still within the cooling range of liquid nitrogen.

The key point is that the simulation data of the critical magnetic field has been increased from the original 20T to 37T, and the maximum value has reached 47T, which is almost more than twice as much.

"Beautiful! The critical magnetic field of 40T is definitely strong enough!"

Looking at the A4 paper still exuding warmth and the fragrance of ink in his hand, Xu Chuan's pupils were filled with joy and excitement.

The huge increase in the critical magnetic field undoubtedly confirmed his previous theoretical calculations.

If this kind of superconducting data can be reproduced in the next real experiment, there is no doubt that there is hope for miniaturized controllable nuclear fusion and aerospace engines!

The critical magnetic field of 40T can easily reach over 60T or even higher through magnetic field superposition.

This level of magnetic field strength can be greatly improved on the existing basis, whether it is for constraining high-temperature plasma or constructing an accelerating magnetic field.
