硬质高岭土煅烧及添加剂增白的研究

以湖北某地硬质高岭土为试样，研究了煅烧过程中其白度的变化规律，成功地找到了提高该矿区煅烧高岭土白度较有的添加剂。同时，对高岭土的煅烧增白和添加剂ＮａＣｌ的增白机理作了较为深入的探讨。

Study on Hard Kaolin Roasting and Additive Whitening

With a hard kaolin ore in Hubei province as the sample,its whiteness change law in the roasting process was studied and an efficient additive for improving the roasted kaolin whiteness of this mine district was successfully found.Meanwhile,deep investigation on the mechanisms of kaolin whitening by roasting and NaCl additive was made.
