the anatase present in the kaolin deposits has an intense reddish-brown color. This color is likely due to substitution of 2 to 5% iron (expressed as % Fe2O3) for titanium in the crystal lattice of the anatase. As the anatase is removed from the kaolin, substantial brightness improvement of the remaining kaolin is obtained.

As kaolin binds to polymers during processing, it naturally enhances mechanical properties, including strength, impact and flexibility. Kaolin gives plastics and rubbers desirable properties, like better resistance to tears and abrasions. It also improves these products' tensile strength and prevents warping.

The effect of dry grinding of kaolin minerals by a mechanical mortar was examined by x-ray, thermal, and electron microscopic methods. Base exchange capacity and apparent density were also measured. In the early stage of grinding, kaolin crystals cleave and fracture and then split into fine crystals which are considered unit crystallites. Such crystallites …
