TC titanium dioxide is the use of inorganic material modification and composite technology, composite powder by crystallization of TiO2 and inorganic solid materials in the preparation of the surface of the coated particles. A surface layer of titanium dioxide TiO2 TC because the nature and effect of the integrated multi-component composite material similar in nature to form the titanium dioxide pigment. TC portion containing the main raw material of titanium dioxide is relatively inexpensive inorganic component, prepared under reaction conditions Cleaning pollution, and therefore the manufacturing cost thereof is relatively large as compared with the reduction of titanium dioxide.
