Hydrolysis of Titanyl Sulfate Solution and Characterization of Product in Ultrasonic Wave Field

WU Pan, ZHANG Zhao (College of Chemical Engineering, Sichuan University, Chengdu 610065, China)  
Investigated was the hydrolysis process of titanyl sulfate without adding external seed in ultrasonic wave field. The product of hydrolysis was characterized by XRD , SEM, TEM and EDS. Experimental results indicated that the product of hydrolysis was anatase-TiO2.Compared with the product obtained without ultrasonic wave irradiation, the crystal structure and grain size of hydrolysis product have been changed. Effect of ultrasonic wave irradiation on hydrolysis of titanyl sulfate solution and crystallization process was discussed preliminarily.
