Description of Calcium Fluoride Powder

Designations: 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. Our product is 100% domestically mined and packaged in the United States.

  • Potential Health Hazards of Calcium Fluoride:
    The hazards of calcium fluoride are due primarily to the harmful effects of its fluorine and silica content. Acute inhalation may cause gastric, intestinal, circulatory and nervous system problems. Chronic inhalation or ingestion may cause loss of weight and appetite, anemia, 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 fibro-genic action of silica in the lungs. Cases of bronchitis and silicosis have been reported among fluorspar miners.
