超声波对制备超细氧化锌的影响

摘要

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.%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200 nm.
