纳米氧化铟的制备

Preparing of Nanometer In_2O_3

基于并流沉淀法,采用超声波分散技术和表面包覆技术制备纳米氧化铟,讨论了底液组成、搅拌速度、分散剂种类、前驱体煅烧条件、超声波处理等对纳米氧化铟制备的影响。用XRD、TEM、IR和TG/DTA对前躯体和产品纳米氧化铟的形貌和粒度进行表征,结果表明:基于并流沉淀法,采用超声波分散技术和表面包覆技术所制得纳米氧化铟呈球形、粒度分布均匀且范围窄,平均粒径80 nm。

The nanometer-size In2O3 is produced by surface-coated and ultrasonic radiation base on paralled flow precipitation process. The factors such as, composing of bottom liquid, speed of stirring, category of dispersant, dryness and calcine condition of precursor, ultrasonic radiation on the preparation of nanome- ter-size In2O3, are analyzed. The sharp and granularity of precursor and nanometer-size In2O3 was characterized by XRD, TEM, IR and TG/DTA. The results show that nanometer-size In203 is spheroidal; granularity is well-distributed and arrow-dispersed, the average diameter size is 80 nm.
