· JVASP-120529· KMg3AlSi3O11F

KMg₃AlSi₃O₁₁F is a fluorine-bearing silicate ceramic belonging to the mica family, specifically a potassium magnesium aluminosilicate with fluorine substitution. This material is primarily used in high-temperature electrical and thermal applications where its layered silicate structure provides excellent insulation properties and chemical stability. The fluorine content enhances mechanical performance and thermal resistance compared to standard micas, making it valuable in demanding aerospace, electronics, and industrial heating environments where conventional ceramic insulators 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.
