Micro titania with small size, narrow size distribution, nice dispersibility, and spherical shape has been broadly used in many fields such as paintings, plastic cements, printings, papers, metallurgies, makeups and so on, for its high refractive index, good whiteness, large surface, good lightproof and weatherproof,Titanium salt is easy to hydrolysis and hydrolytic rate is difficult to control.
