· JVASP-21065· ThB4Mo

ThB4Mo is a refractory metal boride compound combining thorium, boron, and molybdenum, belonging to the family of transition metal borides known for exceptional hardness and thermal stability. This material is primarily of research and specialized industrial interest for ultra-high-temperature applications where conventional superalloys reach their limits, such as in aerospace propulsion systems, nuclear reactor components, and extreme-environment cutting tools. The addition of molybdenum to the thorium-boron system enhances toughness and oxidation resistance compared to simpler boride phases, though ThB4Mo remains an emerging material with limited commercial production.

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.
