Ho2Sn2O7
ceramic· JVASP-19078· Ho2Sn2O7
Ho₂Sn₂O₇ is a rare-earth tin oxide ceramic belonging to the pyrochlore family, composed of holmium and tin in a ordered cubic crystal structure. This material is primarily investigated in research contexts for high-temperature applications and as a thermal barrier coating candidate, where its rare-earth content and ceramic stability offer potential advantages in extreme thermal environments. The pyrochlore family is notable for exceptional thermal stability and low thermal conductivity, making compounds like this candidates for aerospace and energy applications, though Ho₂Sn₂O₇ remains largely in the experimental phase compared to established thermal barrier coating systems.

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.
