· JVASP-120497· TaSi4Mo

TaSi₄Mo is a refractory intermetallic compound combining tantalum, silicon, and molybdenum—materials traditionally valued for extreme-temperature stability and hardness. This is primarily a research-phase material designed to explore high-performance ceramic-metallic hybrids, with potential applications in ultra-high-temperature structural components where conventional superalloys reach thermal limits. The tantalum-silicon matrix provides oxidation resistance and hardness, while molybdenum addition aims to improve toughness and thermal shock resistance; however, practical engineering use remains limited pending further processing development and cost-benefit validation against established alternatives like titanium aluminides or silicon carbide composites.

Export Control

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.
