- Calcium Fluoride Synonyms:
CaF2, calcium fluoride, fluorspar, fluorite, acid-spar, calcium difluoride, fluorspan, met-spar, CAS# 7789-75-5, CaF2 crystals, crystalline calcium fluoride
Chemical Name: Calcium fluoride
Chemical Formula: CaF2
Calcium fluoride is a mineral composed of CaF2. It occurs as cubic, isometric crystals and cleavable masses. When pure, it is colorless and transparent, or translucent with a glassy luster. Impurities cause color in the stone, and several varieties exhibit fluorescence. Usually found either in pure veins or associated with lead, silver, or zinc ores, it is common in limestone and dolomites. Fluorite occurs in England and the United States.
1) Crude ore- 25 to 30%
2) Metallurgical grade- 75 to 82%
3) Ceramic grade- 94 to 96%
4) Acid grade- 97%
5) Crystalline grade- 99%

- Calcium Fluoride Potential Health Hazards:
The hazards of calcium fluoride are due primarily to the harmful effects of the fluorine content and its silica content. Acute inhalation may cause gastric, intestinal, circulatory and nervous system problems. Chronic inhalation or ingestion may cause loss of weight and appetite, anaemia, and bone and teeth defects. Pulmonary lesions have been reported among persons inhaling dust containing 92 to 96% calcium fluoride and 3.5% silica. It appears that calcium fluoride intensifies the fibrogenic action of silica in the lungs. Cases of bronchitis and silicosis have been reported among fluorspar miners.
