Product Description

                                                                                               Calcium Fluoride 


Mainly used as a flux in the manufacture of steel in basic open hearth, basic converter and electric hearth in Metallurgic industry.
It can enhance the fluidity of slag and promote the entry of sulfa and phosphor into slag, 
Thus improve the quality of steel. It can also be used in metallurgy of non-ferrous metal, welding material, optical elements,
decoration flamp sand lanterns and fluorspar carving craftwork.

Physical and Chemical Properties
Crystal structure: belongs to the isometric crystal system, cubic, octahedral or dodecahedral. Colourless crystals or white powder,
natural ore contains impurities, slightly green or purple. Luminous when heated. Density 3.18g/cm3, melting point 1402°C,
boiling point 2500°C, refractive index 1.434. Low toxicity. Extremely difficult to dissolve in water. Soluble in hydrochloric acid,
hydrofluoric acid, sulfuric acid, nitric acid and ammonium salt solution, insoluble in acetone. Dissolved in aluminium salt and iron
salt solution to form a complex, and hot concentrated sulfuric acid to generate hydrofluoric acid. Hydrogen fluoride can be produced
by reacting calcium fluoride with concentrated sulphuric acid in a lead container. It can form low co-melts with many metal oxides.
