K1 Al1 S2 O8

ceramic

· K1 Al1 S2 O8

K1Al1S2O8 is an aluminosilicate ceramic compound containing potassium, aluminum, sulfur, and oxygen—a composition that places it in the feldspar or sulfate-modified aluminosilicate family. This material is likely used or researched for applications requiring moderate stiffness and hardness, such as refractory components, electrical insulators, or specialty ceramics where both thermal and mechanical stability are needed. The presence of sulfur suggests potential applications in sulfate-resistant formulations or specialized high-temperature environments where conventional feldspathic ceramics may degrade.

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.
