Production of titanium dioxide

Depending on the process used, potassium chloride, potassium sulphate or magnesium sulphate can be used as a processing aid for calcination in the production of titanium dioxide.

During calcination the product quality (especially the particle size and degree of whiteness) of titanium dioxide is adjusted. The level of quality (the higher the better) of the processing aids used will also have a positive effect on controlling the production process.
