KAlSi3O8
ceramic· JVASP-144185· KAlSi3O8
Potassium feldspar (orthoclase), a common aluminosilicate ceramic mineral with the formula KAlSi3O8. This naturally occurring compound is one of the most abundant minerals in Earth's crust and serves as a primary constituent in engineered ceramic and glass formulations. Engineers select feldspar-based ceramics for their chemical stability, low thermal expansion, and cost-effectiveness in high-volume applications; it functions both as a primary phase and as a flux to lower sintering temperatures in whiteware bodies and glass manufacture.

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.
