· JVASP-118482· ScHO

ScHO is a rare-earth oxide ceramic compound combining scandium and holmium oxides, belonging to the family of lanthanide-based ceramics. This material is primarily of research interest for high-temperature structural applications and photonic devices, where its crystalline oxide matrix offers thermal stability and potential optical properties. While not yet established in mainstream engineering production, ScHO represents the broader class of mixed rare-earth ceramics being investigated for extreme environments where conventional oxides reach their limits.

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.
