· JVASP-112601· CaAlSiO5

CaAlSiO₅ is a calcium aluminosilicate ceramic compound that forms part of the anorthite mineral family, commonly encountered as a phase in high-temperature ceramic and refractory systems. This material is primarily of interest in industrial ceramics, cement chemistry, and refractory applications where it provides thermal stability and structural integrity at elevated temperatures. Engineers select this composition and related phases for their chemical durability, low thermal expansion, and ability to maintain strength in harsh thermal environments, making them valuable alternatives to pure alumina or silica-based ceramics in applications requiring phase stability across broad temperature ranges.

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.
