摘　　要：实验研究以传统的铬酸酐热分解法制备Cr2O3工艺为基础，考察了不同的反应温控条件（中高温段）对Cr2O3烧成品性状的影响，通过对比1000，1200，1300℃等不同温度阶段下物料烧结的效果，探讨了三氧化二铬微粒烧结长大的一般规律。The experimental study in this paper was based on the traditional preparation process of chromium oxide from chromic anhydride by the thermolysis method. The influence of different reactive temperature on the properties of final - sintered chromium oxide product was investigated. The exploitation of the general growth rule of chromium oxide particle was made, through the comparison of sintering results in different temperature （ medium and high temperature stage）, such as 1 000,1 200 and 1 300 ℃ etc..
