· JVASP-107348· Er2Si3

Er2Si3 is an erbium silicate ceramic compound belonging to the rare-earth silicate family, characterized by a crystalline structure combining erbium oxide with silicon. This material is primarily of research and development interest for high-temperature structural applications, particularly in aerospace and thermal barrier coating systems where rare-earth silicates offer improved oxidation resistance and thermal stability compared to conventional zirconia-based ceramics. Er2Si3 is notable for its potential use in next-generation thermal protection systems and environmental barrier coatings for advanced gas turbines and hypersonic vehicles, where its rare-earth composition provides superior performance in oxidizing environments at extreme 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.
