· JVASP-153671· HoB12

HoB12 is a boride ceramic compound combining holmium with boron, belonging to the rare-earth boride family of ultra-hard ceramics. It is primarily of research and developmental interest for extreme-environment applications where hardness, thermal stability, and chemical resistance are critical. This material class is explored for potential use in cutting tools, wear-resistant coatings, and high-temperature structural applications where conventional ceramics fall short, though commercial deployment remains limited compared to established borides like TiB2.

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.
