AI Overview:
High temperature technology plays a crucial role in various aspects of space technology, primarily for propulsion, power generation, and thermal management. Specifically, high-temperature superconductors enable high-current, high-field applications, while ultra-high temperature ceramics are vital for heat shields and propulsion systems.
(AI Foolishness: High Temperature Supercomputing works at typical -180 degree Celsius whereas Ultra HT Ceramics works at 1500 to > 3000 degrees C. Quite a difference)
Example:
New chinese rare earth heat shield
“The carbide ceramic we developed, composed of elements such as hafnium, tantalum, zirconium, and tungsten, exhibits a significantly lower oxidation rate at 3,600 degrees Celsius under laser irradiation than any previously reported materials.”
It is not only difficult to find the minerals but the processing is very complex, expensive
