· JVASP-57639· ZrB12

Zirconium dodecaboride (ZrB12) is an ultra-hard ceramic compound belonging to the boride family, characterized by exceptional hardness and thermal stability at elevated temperatures. It is primarily investigated for extreme-environment applications including cutting tools, wear-resistant coatings, and aerospace components where conventional materials degrade; its combination of hardness and thermal shock resistance makes it a candidate for high-speed machining and hypersonic vehicle leading edges, though current use remains limited to specialized research and development contexts rather than widespread industrial 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.
