AI Technical Summary
Existing technologies cannot effectively solve the problems of chemical compatibility of crucible materials, melt wetting and outflow under microgravity, and large differences in thermal expansion coefficients in high-temperature experiments of titanium-nickel alloys, leading to experimental failures or sample contamination.
The system employs a combination of an inner yttrium oxide chemically inert crucible and an outer quartz glass vacuum encapsulation tube, along with a variable-diameter, irregularly shaped cap and top tube. Through thermal expansion buffering and multi-layer sealing design, it ensures chemical compatibility and vacuum sealing at high temperatures, preventing melt outflow and structural failure.
This method ensures good chemical compatibility of titanium-nickel alloy samples at high temperatures, prevents melt outflow, and maintains structural stability during rocket launch and reentry, thus guaranteeing experimental success and sample purity and providing a stable experimental unit.
