· JVASP-105391· TaTiB4

TaTiB4 is a refractory metal boride compound combining tantalum, titanium, and boron, belonging to the family of ultra-high-temperature ceramic materials and metal borides. This material is primarily of research and development interest for extreme-environment applications where conventional metals and ceramics reach their performance limits. Engineering interest centers on potential applications requiring exceptional hardness, oxidation resistance, and thermal stability, though industrial adoption remains limited and the material's practical processability and cost-effectiveness continue to be evaluated against established alternatives.

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.
