Anorthite (CaAl₂Si₂O₈) is a calcium alumina silicate ceramic belonging to the plagioclase feldspar mineral family, commonly found as a natural mineral phase and engineered ceramic constituent. It is widely used in refractory applications, glass-ceramics, and porcelain formulations due to its thermal stability and low thermal expansion. Engineers select anorthite-based materials for high-temperature environments where chemical inertness and dimensional stability are critical, and it serves as a key phase in engineering ceramics competing with alternative refractories through its balanced combination of mechanical strength retention at temperature and cost-effectiveness.

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.
