This work was undertaken to elucidate the relationship between various characteristics of ceramic materials and their chemical composition, and to establish standard methods of chemical analysis for the standard ceramic materials to be used for fluorescent X-ray analysis. Therefore, various sample decomposition methods and measurement methods were developed for the chemical analysis of ceramics and related materials. In the first study, non-oxide ceramics samples were analyzed for the content of silicon nitride, silicon carbide, and boron carbide. In the analysis of silicon nitride, a determination method for small amounts of fluorine and surface oxygen was also established. With these tests, the relationship between the conditions of the sample synthesis and the chemical composition had been clearly shown. In the second study, the analysis samples were made of the oxide ceramics zirconium oxide, zinc oxide and lanthanum manganites. A determination method was established for silicon in zirconium oxide, and then silicon and aluminum in zinc oxide. The precision of the valence determination method of manganese in lanthanum manganites was also improved. The third study describes the chemical analysis methods for impurity elements in carbon and sulfur. This study establishes chemical analysis methods for the main component and impurity elements in fine ceramics and related materials.
