· 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.

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
