· JVASP-130741· Ho8B

Ho8B is a holmium boride ceramic compound that belongs to the rare-earth boride family, materials known for their exceptional hardness and thermal stability at high temperatures. This material is primarily of research and development interest for applications requiring extreme hardness and thermal resistance, particularly in cutting tools, wear-resistant coatings, and high-temperature structural applications where conventional ceramics reach their performance limits. Holmium borides are explored as alternatives to established carbides and nitrides when superior oxidation resistance or specialized thermal properties are needed, though industrial adoption remains limited compared to more mature ceramic systems.

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.
