对硅铁红色料中铁的穆斯堡尔谱研究

MOSSBAUER SPECTROSCOPIC STUDY ON Fe OF SILICON-IRON-PEACH PIGMENT

采用ＸＲＤ、ＤＴＡ－ ＴＧ 测试方法研究了硅铁红色料中的矿物组成及热处理过程中的物化变化，在此基础上，利用ｍｏｓｓｂａｕｅｒ 谱分析了Ｆｅ 的存在形式，价态及其随温度变化的规律，得出几点结论，为进一步探讨该色料的呈色机理提供指导。

Based on the study on the crystal phase of the sililon-iron-peach pigment,the physical-chemical changes during heat treatment by XRD.DTA-TG,this paper analysed the state,valence and the change of Fe in the heating process by mossbauer,reached several valuable conclusions,and provided a guicle to probe into the colonr development mechanism of this pigment.
