· JVASP-35632· HoO3

Holmium trioxide (HoO3) is a rare-earth ceramic oxide compound belonging to the lanthanide oxide family. While not widely established in conventional engineering applications, holmium oxides are studied primarily in advanced optical, magnetic, and nuclear materials research due to holmium's unique electronic and magnetic properties. This material represents an emerging research compound rather than a mature industrial material; it is of interest to specialists in rare-earth ceramics, optoelectronics, and nuclear/radiation applications where lanthanide elements offer distinctive capabilities.

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.
