摘要
采用直接沉淀法,在特定超声频率下制得超细氧化锌产品。研究了3种沉淀剂通过超声波后对制备超细氧化锌产品的影响,经超声制备的产品分散性好、粒度小。确定了最佳超声时间为50min,超声强度为40%。通过SEM检测可知,在最佳条件下制得的超细氧化锌产品为类球形,晶粒内部有中空孔洞,其粒径约为200nm。
Superfine zinc oxide particles were prepared by using direct precipitation method under a certain ultrasonic frequency.The changes of the products under ultrasonic with three different raw materials were studied.The optimum ultrasonic time is 50 min and the optimum ultrasonic strength is 40%.The optimized superfine zinc oxide products are spherical like with hollow holes in the grain,and the particle diameter is about 200 nm.
