Ca2 Mg5 Si8 O22 F2
ceramic· Ca2 Mg5 Si8 O22 F2
Ca₂Mg₅Si₈O₂₂F₂ is a calcium magnesium silicate fluoride ceramic belonging to the amphibole mineral family, characterized by a layered silicate structure with fluorine substitution. This composition is primarily known as tremolite or a tremolite-family mineral and is used industrially in refractory applications, insulation systems, and historically in asbestos-alternative fibrous materials where thermal stability and chemical inertness are required. The fluorine-substituted variant offers potential advantages in specialized high-temperature ceramics and research applications exploring biocompatible or low-toxicity alternatives to traditional amphibole minerals.

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.
