· JVASP-131476· HoB11

HoB11 is a rare-earth metal boride ceramic compound combining holmium with boron, belonging to the hexaboride family of materials. These ceramics are of significant research interest for high-temperature applications and advanced functional materials, particularly where thermal stability and hardness are critical. Hexaborides like HoB11 are being investigated for thermionic emission devices, refractory applications, and potential use in extreme environment components, though commercial adoption remains limited compared to more established 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.
