· JVASP-25585· Ca2Mg5Si8O22F2

Ca2Mg5Si8O22F2 is a calcium magnesium silicate fluoride ceramic belonging to the amphibole mineral family, characterized by a layered silicate structure with incorporated fluorine. This material is primarily studied in research contexts for high-temperature applications and as a constituent phase in advanced ceramic composites, where its thermal stability and low density make it of interest for aerospace and refractory applications. Compared to conventional silicate ceramics, the fluorine incorporation and magnesium-rich composition may offer advantages in thermal shock resistance and processing flexibility, though industrial adoption remains limited to specialized roles in composite matrices and experimental high-performance systems.

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.
