use of feldspar & flourspar in white cement

Fluorspar is added to help the combination of the kiln feed into the white cement clinker so reducing the fuel (pet coke) consumption of the kiln. Feldspar is added to correct the alkali:sulphate balance in the kiln. Petcoke is high in sulphur so the feldspar provides additional alkali to balance that. As the feldspar is finer than the raw mill ...

Traditional ceramics | Clay, Glazing & Firing Techniques

Silica and feldspar. Other constituents of traditional ceramics are silica and feldspar. Silica is a major ingredient in refractories and whitewares. It is usually added as quartz sand, sandstone, or flint pebbles. The role of silica is that of a filler, used to impart "green" (that is, unfired) strength to the shaped object and to maintain that shape during firing.

Feldspar

In ceramics and glass production, feldspar is used as a flux. A flux is a material that lowers the melting temperature of another material, in this case, glass. Substitutes and Alternative Sources. Feldspar can be replaced by other minerals and mineral mixtures of similar physical properties. Minerals that could be used to replace feldspar ...
