　 CAS No.:  7789-75-5
　 Description:  　

    Molecular formula:  CaF2 　
    Application:
1. It is the main material to produce the fluorine and fluoride. It is used in the production of fluorescent screens,
    fluorescent lights and other fluorescent powder as a new type of electric light source material, and also can
    be used for the metallurgical, chemical, water, glass, ceramics and so on.
2. It is the essential raw material which make of high-quality, artificial crystal of calcium fluoride . And it used in
    optical instruments, optical glass and high purity demanding of other optical industries
3.  The high pure products is the essential raw material to produce calcium fluoride coating material with the high
    purity and without  collapsing point.
