Preparation technology and industrialization production of nanometer TiO_2 using metatitanic acid as raw material;

Preparation of nano-TiO_2 powders with metatitanic acid and its photo-catalytic properties;

Experimental study on flocculating fine metatitanic acid by modified polyacrylamide;

With the starting material intermediate titanyl sulfate and meta-titanic acid of titanium white product by sulfuric acid process,the titanium dioxide and iron content have been determined.

Using filtrate theory the washing rule of Meta-titanic acid in the prodution of titanium pigment was studied, the influential factor was analyzed, consequently some way, to decrease washing time of meta-titanic acid were also presented.
