· JVASP-143743· Ca2AlSi2O7

Ca₂AlSi₂O₇ is a calcium aluminosilicate ceramic belonging to the anorthite-family compounds, which are silicate ceramics formed through high-temperature synthesis. This material is primarily encountered in refractory applications, cement chemistry, and geological materials, where its thermal stability and phase composition make it valuable for environments requiring resistance to thermal shock and chemical attack. Engineers select this composition for applications demanding moderate-temperature ceramic performance and compatibility with silicate-based systems, though it is less commonly specified as a standalone engineering ceramic compared to alumina or zirconia alternatives.

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.
