Titanium dioxide is a very important raw material in industrial production. It is used in paint, ink, plastic, rubber, paper, chemical fiber and other industries; it is used for welding electrodes, titanium extraction and the manufacture of titanium dioxide.

Titanium dioxide (nano-level) is widely used in white inorganic pigments such as functional ceramics, catalysts, cosmetics and photosensitive materials. It is the strongest coloring power among white pigments, has excellent hiding power and color fastness, and is suitable for opaque white products. The rutile type is especially suitable for plastic products used outdoors, and it can give the products good light stability. Anatase is mainly used for indoor products, but it has a slight blue light, high whiteness, large hiding power, strong coloring power and good dispersion.
