Titanium Dioxide is a kind of white pigment, they have two types: Rutile Titanium Dioxide and Anatase Titanium Dioxide.

Rutile type and Anatase type Titanium Dioxide belong to tetragonal crystal system. Rutile Titanium Dioxide is the most stable crystalline forms, it compared with Anatase type, Rutile type have higher hardness, density, dielectric constants and refractive index.

Titanium Dioxide have two production methods: Sulphate process and Chlorination process.

Sulphate process can manufacture Rutile Titanium Dioxide and Anatase Titanium Dioxide.

Chlorination process only can manufacture Rutile Titanium Dioxide.
