摘　　要：以低浓度工业钛液所制偏钛酸为原料,采用四元二次回归正交组合设计考察盐处理剂加量(锌盐、钾盐、磷盐)和煅烧段最高温度的正交交互作用影响,对偏钛酸进行粒度、XRD表征分析,并测试样品消色力指标,建立有效回归模型,预测钛白质量。最佳盐处理煅烧条件为:ZnO 0.36%,K_2O 0.70%,P_2O_50.20%,高温段煅烧温度850℃,试验值与预测值吻合度较好。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 K_2O and 0. 20% of P_2O_5 with 850°C of highest calcination temperature. The experimental results fit well with the predicted values.
