Er2Si2O7
ceramic· JVASP-10079· Er2Si2O7
Er2Si2O7 is a rare-earth silicate ceramic compound combining erbium oxide with silica, belonging to the family of rare-earth disilicates used in high-temperature structural and functional applications. This material is primarily investigated for thermal barrier coatings, refractory linings, and advanced ceramic matrix composites in aerospace and industrial gas turbine environments where thermal stability and chemical resistance are critical. Er2Si2O7 offers potential advantages over conventional alumina-based ceramics in corrosive, high-temperature service due to its rare-earth composition, though it remains largely in research and specialized industrial development rather than commodity use.

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.
