· JVASP-98449· K2Al2Si3O10

K2Al2Si3O10 is a potassium aluminosilicate ceramic belonging to the feldspar mineral family, commonly known as orthoclase or a related feldspar polymorph. This material is widely used in traditional ceramics, glass, and refractories due to its stable crystal structure and thermal properties, making it a foundational component in industrial silicate systems rather than a standalone engineering ceramic.

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.
