FT-IR spectrometry was applied to the quantitative chemical state analysis of several kinds of ceramic powders. In a few experiments, the particle size of the sample powder affected the peak intensity on the FT-IR/DR spectrum. The particle size of a component in the multiple component sample could be determined by measuring the intensity ratio between two peaks specific to the component. And the concentration of the component could be determined by comparing the peak intensity with that of pure powder having the same particle size. FT-IR/PAS and laser induced thermal emission spectrometry were also studied. ICP-AES and AAS were applied for the purpose of high sensitivity analysis of the metallic impurities in ceramic powders. The optimum methods of sample decomposition and for measuring the concentration of impurities in four kinds of ceramics (Si_3N_4,SiC, Al_2O_3 and ZrO_2) were proposed. For SiC, two decomposition methods (Na_2CO_3 fusion of whole sample and acid extraction of impurities) were studied. The results showed that most impurities were condensed on the surface of SiC particles.
