Ca2 Al4 Si2 O12
ceramic· Ca2 Al4 Si2 O12
Ca₂Al₄Si₂O₁₂ is a calcium aluminosilicate ceramic compound belonging to the family of synthetic minerals and industrial ceramics. This composition is related to anorthite and gehlenite mineral phases, which form as intermediates in high-temperature ceramic systems and are commonly encountered in portland cement chemistry, refractory materials, and engineered ceramic matrices. Engineers select this phase or ceramics containing it for applications requiring thermal stability, chemical resistance, and mechanical strength at elevated temperatures, particularly in systems where alumina and silica sources naturally combine with calcium oxides.

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.
