STUDY ON INFRARED ABSORPTION SPECTROMETRY IN SOLID PHASE REACTION OF THE Kta_(0.4)Nb_(0. 6)O_3 FERROELECTRIC CERAMICS

利用红外吸收光谱分析方法，研究固溶体钽铌酸钾铁电陶瓷原料在预烧阶段中的固相反应，观察ＫＴＮ材料的中心离子与氧离子键的特征吸收峰的生成过程，判断固相反应完成的程度，确定ＫＴＮ陶瓷的预烧温度，与Ｘ射线衍射结构分析和预烧温度对瓷体密度的影响结果比较，发现红外吸收光谱分析方法是确定铁电陶瓷预烧温度的另一种可靠方法。

Using infrared absorption spectrometry,it is studied that solid phase reaction of solid-solution KTa0.4Nb0.6O3 ferroelectric ceramic material in calcining period.By obserying production process of absorption peak of KTN Oxygen octahedron center ion and oxygen ion bonds,new synthetic compound is determined.Comparing with x-ray diffraction structure analysis,with the dependence of the ceramic density for calcining temperature.we find that the infrared absorption spectrometry provides another method of determination calcining temperature of ferroelectric ceramics.
