微乳纳米反应器制备单分散性球形氧化铬超细粉的研究
Preparation of Mono-dispersed Spherical Superfine Cr2O3 Powder in Microemulson System
【摘要】 将表面活性剂加入到一种热稳定性有机介质中作为油相 ,铬 (Ⅵ )盐溶液中加入某种还原助剂作为水相 ,制成W /O型微乳纳米反应器 ,利用该技术制备出了不同粒度范围内的单分散球形氧化铬 (Ⅲ )超细粉体
【Abstract】 Spherical superfine chromiun(Ⅲ) oxide powder of different sizes and size distributions are prepared by in a W/O microemulsion system.It is shown that the parameters of microemulsion reactor,the heating treatment have a significant influence on the performance of the particles.
