This time, the superconducting antigravity experiment also used a niobium alloy material.
At the beginning of the experimental preparations, others suggested using pure niobium metal, as its superconductivity would be somewhat better, but considering the cost of creating ultralow temperatures, they ultimately chose the niobium alloy.
In fact, for Zhao Yi, the type of superconducting material wasn't very important, because the performance differences between superconducting materials are quite minor. Perhaps to others, a better superconducting material would seem to make the experiment more likely to succeed, but Zhao Yi didn't rely on his eyes to judge the success of the experiment; a single cost-free use of "Causality Law" was enough.
Therefore, it was still best to save funds where possible, avoiding unnecessary expenses.
Finally.
It was nine o'clock.
Li Ning couldn't wait to remind, "It's almost nine, Academician Zhao."
