用XPS测定汝瓷月白釉挂红中Fe和Cu的形态

INVESTIGATION OF Fe AND Cu SHAPES OF RED DECORATED MOON-WHITE GLAZE ON RU WARE BY XPS

本文针对前人对铜红釉和钧红着色的不同研究结果,选用XPS对铜和铁在釉中存在形态进行了测定,得到了汝瓷月白釉挂红中着色元素Fe和铜的XPS曲线,由测得电子能谱与其标准谱进行比较得到,釉中Fe是以FeO,Fe_3O_4,和Fe_2O_3多种氧化物着色,且以Fe_3O_4为主;而Cu则是以CuSiO_3形态存在,实验没有发现一价铜的2P_(3/2)电子谱。文章进一步用热力学分析了汝瓷月白釉挂红的烧制工艺,得到与以往用热力学分析相似的结果。

According to the different investigation results by predecessors about coloration of the copper - red glaze and Jun-red glaze, the existing shape of Cu is determined by XPS. The XPS curves of colorated elements Cu and Fe in red-decorated moon-white glaze on Ru ware are obtained. By the comparation of testing energy spectrum with standard energy spectrum ,we got that Fe colorates with FeO ,Fe3O4 and Fe2O3 multi -oxide shapes and Fe3O4 plays the important role. Cu exists in CuSiO3 shape. 2P3/2electron spectrum of Cu+ is not discovered in experiment. The sintering technology of red decorated moon - white glaze on Ru - ware is analyzed further by thermodynamics.
