· JVASP-124813· TcAs

TcAs is a technetium arsenide ceramic compound, representing an intermetallic ceramic in the transition metal-pnictide family. This is a research-stage material studied primarily for its potential in nuclear applications and high-temperature structural applications, given technetium's nuclear properties and the ceramic's expected thermal stability. While not yet commercialized at scale, materials in this class are of interest for specialized aerospace and nuclear engineering contexts where extreme temperature resistance and radiation tolerance may be critical.
