· JVASP-146197· Ho5Si2B8

Ho5Si2B8 is a rare-earth borosilicate ceramic compound containing holmium, silicon, and boron—a composition family explored primarily in materials research for specialized high-temperature and functional ceramic applications. This material belongs to the rare-earth boride/silicate family and is not a widely commercialized engineering ceramic; it represents experimental research into advanced ceramic compositions where the rare-earth element (holmium) is combined with refractory boron and silicon networks to tailor thermal, optical, or magnetic properties. Engineers would consider this material only in R&D contexts where custom ceramic performance (such as thermal stability, neutron absorption, or specific optical behavior) justifies development, rather than as a ready-to-specify commodity ceramic.

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.
