· JVASP-140431· KAlSi3O9

KAlSi3O9 is a potassium aluminosilicate ceramic belonging to the feldspar mineral family, characterized by a framework silicate structure. It appears naturally as orthoclase feldspar and is widely used in traditional ceramics, glass manufacturing, and porcelain production where it serves as a flux to lower melting temperatures and improve workability. Engineers select feldspathic materials for applications requiring chemical durability, thermal stability, and cost-effectiveness, though modern high-performance applications often favor engineered ceramics with more precisely controlled properties.

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.
