摘　　要：研究新型无毒无机颜料,逐步取代如铅铬黄、镉黄等无机颜料,日益引人注意。我们以价廉易得的自云石凹凸棒、蒙脱石、凹凸棒石粘土矿为原料,制得黄色硅酸盐类无毒新型颜料。研究了该类颜料的骨架结构与成分,及其发色机理。工艺过程如下:Nonpoisonous inorganic pigments have been prepared from natural clay minerals:dolomitie attapulgite, monlmorillonite, and attapulgite. Pigmental colour was measured on the basis of Munsell renotation system. The composition and the framework structure of the pigments have been studied using XRD, EDAX and XPS techniques. The results showed that the ehromophone of the yellow pigments may be ascribed to the sulphur atoms with oxidation number+4 in the framework of the pigments.
