· JVASP-104735· HoEr

HoEr is a rare-earth ceramic compound composed of holmium and erbium oxides, belonging to the family of lanthanide ceramics used in specialized high-performance applications. This material is primarily of research and advanced technology interest, leveraging the unique optical, magnetic, and thermal properties inherent to rare-earth combinations for niche industrial uses. Its selection is driven by applications requiring specific spectroscopic behavior, thermal management in extreme environments, or magnetic functionality where conventional ceramics are inadequate.

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.
