沉淀法制备纳米氧化铟粉末

PREPARATION OF In_2O_3 NANO-PARTICLES BY PRECIPITATION METHOD

为了开发适合工业化大规模生产超细且分散性好的In2O3粉体的方法,作者以金属铟、盐酸、氨水为原料,对化学沉淀法制备纳米氧化铟粉末的过程进行了研究。通过严格控制实验条件制备出了单相、分散性好、晶粒尺寸约为30nm,粒度分布范围窄的立方晶系纳米In2O3球形粉末。

In order to develop a suitable method for industrial mass production of In2O3 nano-particles which were ultrafine and good dispersion,the author studied the process of chemical precipitation method using indium,hydrochloric acid,ammonia as raw material.The spherical cubic In2O3 nano-particles were synthesized by controlling the experimental conditions strictly.They were single phase,well dispersed,with the grain size apr.30nm,narrow particle size distribution.
