HoPaO4
ceramic· JVASP-105480· HoPaO4
Holmium orthophosphate (HoPaO₄) is a rare-earth phosphate ceramic compound belonging to the family of lanthanide phosphates, which are typically investigated for their thermal stability, radiation resistance, and potential as host materials in advanced ceramics. This material exists primarily in research and development contexts rather than widespread industrial production, with interest driven by applications requiring thermal barriers, photonic materials, or environments where rare-earth ion incorporation is beneficial for functional properties.

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.
