摘　　要：研究了硫酸氧钛溶液在超声波场中自生晶种的水解过程,并结合XRD,SEM,EDS和TEM等现代测试技术对水解产物进行了表征。结果表明,水解产物为含水的锐钛矿型二氧化钛。与无超声波场的水解产物相比较,由于超声波的作用使水解产物粒子变得均匀而分散,产物的晶格常数c和平均晶粒度减小。同时,对超声辐照影响硫酸氧钛溶液水解和结晶过程的机理作了初步探讨。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.
