· ErSiO3

Erbium silicate (ErSiO3) is a rare-earth ceramic compound combining erbium oxide with silicon oxide, typically investigated for high-temperature structural and functional applications. This material belongs to the rare-earth silicate family, which has gained attention as a potential thermal barrier coating (TBC) material and advanced refractory for extreme environments where conventional oxides may fail. ErSiO3 is primarily of research and development interest rather than a mature commercial material, with potential advantages in thermal stability, oxidation resistance, and chemical durability that make it attractive for aerospace propulsion systems and energy applications operating at elevated temperatures.

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.
