以Co_2O_3作着色剂制备彩色水泥的研究

The Study on the Color Cement Preparation with Co_2O_3 as Pigments

在研究彩色水泥的制备中发现用Co2O3作着色剂时,制备的彩色水泥熟料的颜色与文献及书籍中所提到的有所不同。本研究是在着色剂掺量相同的条件下,分别在正常条件或还原条件下煅烧,所制备的硅酸盐彩色水泥熟料,随着着色剂掺量增加由土黄色向青黑色转变。而在着色剂掺量、煅烧条件相同的情况下所得的高铝水泥熟料为蓝色。

In the study of color cement preparation, we found that the color of the cement with Co2O3 as pigments were diffrent computer whith mentioned in the literature and books.With the same amount of pigments the color cement we prepared, whatever in normal conditions or reduction conditions are khaki to grey black with the different incorpo- ration of. pigments But in the same amount of pigments and same calcinations condition, the high alumina cement is blue.
