TmCrB4
metal· JVASP-143636· TmCrB4
TmCrB4 is an experimental ternary boride compound combining thulium, chromium, and boron—a rare-earth transition metal boride belonging to the family of high-hardness ceramic materials. This research compound has not seen widespread commercial deployment but represents a materials chemistry approach to developing ultra-hard, refractory phases for extreme-environment applications. Engineers and materials scientists investigate rare-earth borides like TmCrB4 for potential use in wear-resistant coatings, cutting tool applications, and high-temperature structural components where conventional ceramics or cermets prove insufficient.
