摘　　要：在不同煅烧温度下煅烧Cr(OH)3·x H2O制备氧化铬绿颜料。研究表明,当煅烧温度为950℃时,制备出的氧化铬绿样本颜色性能较优,为亮绿色;其他煅烧温度所得氧化铬绿的颜色发红、偏暗。对部分氧化铬绿样品进行了X射线衍射(XRD)和扫描电子显微镜(SEM)分析,发现通过控制煅烧温度可制备出颗粒均匀的氧化铬绿,颜色性能较优。Cr2O3 was prepared by calcinating Cr( OH)3·x H2O at different temperatures. The studies indicated that the color performance of Cr2O3 sample calcinated at 950 ℃ was excellent and comparable to that of the commercial pigment. The color performances of Cr2O3 samples calcinated at other temperatures were much darker and more reddish. Some of the obtained Cr2O3 samples were characterized by means of XRD and SEM. The results showed that Cr2O3 of a superior color performance and uniform sizes could be obtained by controlling its calcination temperature.
