· JVASP-20965· HoPO4

Holmium phosphate (HoPO4) is an inorganic ceramic compound belonging to the rare-earth phosphate family, typically studied as a dense oxide ceramic with potential applications in high-temperature and radiation-resistant environments. While not widely commercialized as a bulk structural material, holmium phosphates are investigated in research contexts for nuclear fuel applications, thermal barrier coatings, and specialized optical/photonic devices due to the unique properties of holmium as a lanthanide element. Engineers considering this material should recognize it as an advanced ceramic at the research or prototype stage rather than a mature engineering material with established supply chains.

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.
