Calcium Fluoride - CaF2
Calcium Fluoride is an inorganic compound with the formula CaF2. This highly stable
compound of calcium and fluorine occurs naturally as the mineral fluorite, also called
fluorspar.
Asbury Carbons provides two principal industrial grades of fluorspar: Metallurgical and
Acid grade.
Metallurgical Grade
Acid Grade
Used as a flux to lower the melting point
and lower the viscosity of slag formed
during production of steel. This increases
the effectiveness of the slag in removing
impurities, and simplifies slag removal.
Fluorite may also be used in the
production of Portland cement, where its
ability to flux helps promote the
formation of “clinker” and tri-calcium
silicate.
Used in lubricants, friction products,
welding rod coatings, and other
applications where a high purity fluorite
product is required. Acid grade fluorite
may also be used to flux certain mineral
and ceramic substances, or to lower the
viscosity of melts of these materials. CaF2
can be also be used as a ceramic glue or
sintering aid for some abrasive wheels and
other ceramic components that are
fluorite-compatible.
