Beschreibung
Zusammenfassung:	A fluorite synthetic stone comprises: (a) a glass matrix comprising Ca, Si and O, and having a predetermined weight ratio of Ca to Si; and (b) CaF2 crystals dispersed in the glass matrix at a concentration of at least about 70 wt.%. A method of making fluorite synthetic stones includes formulating a particulate mixture comprising: CaF2 crystals at a concentration of at least about 70 wt.%; and an excipient having a predetermined weight ratio of Ca to Si. Aggregates are prepared from the particulate mixture. The aggregates are heat treated to form a plurality of fluorite synthetic stones, where each synthetic stone comprises: a glass matrix comprising Ca, Si and O; and CaF2 crystals dispersed in the glass matrix at a concentration of at least about 70 wt.%.
