ceramic· JVASP-19065· Er2Sn2O7
Er₂Sn₂O₇ is a rare-earth tin oxide ceramic belonging to the pyrochlore family, composed of erbium and tin in a highly crystalline oxide structure. This material is primarily investigated in research contexts for high-temperature thermal barrier coatings and as a potential host matrix for nuclear waste immobilization, leveraging the chemical stability and refractory properties characteristic of rare-earth pyrochlores. It offers advantages over conventional thermal barrier materials in extreme temperature applications and radiation environments, though industrial deployment remains limited compared to established alternatives like yttria-stabilized zirconia.

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.
