· Ho4 Sc4 O12

Ho4Sc4O12 is a rare-earth mixed oxide ceramic compound combining holmium and scandium oxides in a structured lattice. This material belongs to the family of rare-earth pyrochlore or garnet-like ceramics, which are primarily investigated in materials research for applications requiring high thermal stability and chemical inertness in extreme environments. While not yet widely deployed in mainstream industrial production, this compound is of interest to researchers exploring advanced ceramics for high-temperature structural applications, thermal barrier systems, and specialized optical or magnetic devices where rare-earth dopants provide functional benefits.

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.
