There are mainly two types of Ceramics Raw materials & Chemicals available

1) Barium Carbonate
2) Sodium Tripolyphosphate

Barium Carbonate

Barium carbonate is widely used in the ceramics industry as an ingredient in glazes. It acts as a flux, matting and crystallizing agent and combines with certain coloring oxides to produce unique colours not easily attainable by other means. Its use is somewhat controversial since some claim that it can leach from glazes into food and drink. To provide a safe means of use, BaO is often used in fritted form.

In the brick, tile, earthenware and pottery industries barium carbonate is added to clays to precipitate soluble salts (calcium sulfate and magnesium) that cause efflorescence.

Sodium Tripolyphosphate

Sodium Tripolyphosphate (STPP TPP) is an inorganic compound. Sodium Tripolyphosphate is the sodium salt of the polyphosphate penta-anion, which is the conjugate base of triphosphoric acid. Sodium Tripolyphosphate is produced on a large scale as a component of many domestic and industrial products, especially in ceramic Industry & detergents. Environmental problems associated with eutrophication are attributed to its widespread use.
