With metatitanic acid hydrolyzing from low concentration of industrial titanyl sulphate solution as raw material,the orthogonal mutual influences of the addition amount of salt treatment agents(zinc salt,potassium salt and phosphorus salt) and the highest calcination temperature were investigated by using four-factor quadric orthogonal regression test.The metatitanic acid was characterized by particle size measurement and XRD.The achromic abilities of the calcined samples were measured to establish effective regression model and forecast the quality of titanium dioxide pigment.The optimal conditions of salt treatment and calcination are 0.36% of ZnO,0.70% of K2O and 0.20% of P2O5 with 850℃ of highest calcination temperature.The experimental results fit well with the predicted values.
