· JVASP-131496· TaB11

TaB11 is a tantalum boride ceramic compound belonging to the refractory ceramic family, characterized by extremely high melting temperature and hardness typical of transition metal borides. This material is primarily of research and specialized industrial interest for ultra-high-temperature applications where conventional ceramics and metals reach their performance limits, such as aerospace thermal protection, cutting tools, and wear-resistant coatings. TaB11 offers potential advantages over competing refractory ceramics through superior hardness and chemical stability, though it remains less widely commercialized than established alternatives like tungsten carbide or zirconia due to manufacturing complexity and cost.

Regulatory Screening

Environmental

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.
