| titleOfInvention | Silicon oxynitride ceramics RIP technology and products |
| abstract | PROBLEM TO BE SOLVED: To eliminate the "excessive manufacturing cost compared with steel materials", which is a fundamental problem of silicon nitride, a typical structural ceramic, which is semi-permanently 1) Optimal ceramic composition and synthesis technology + 2) Ceramic water Refinement processing technology + 3) Ceramic forming method and mass production processing technology + 4) Sintering technology + 5) Grinding and polishing technology to product shape were examined in detail based on these individual technologies and their mutual interaction. As a result, it has been found that the main cause is that silicon nitride becomes brittle by hydrolysis during the refining process in water, which is performed for a long time when the primary particles of silicon nitride are refined. SOLUTION: 1) β-Sialon whose quality characteristics after sintering are recognized as technically equivalent to or better than silicon nitride, have a chemical composition of 0.05 ≦ Z ≦ 4.2, and 0.5 μm or less It is solved by a combination of the manufacturing method and technology of primary fine powder particles and the optimum RIP molding method and technology to be performed as the next process. 2) Solving the problem The solution described in 1) is that the combustion synthesis conditions of β-Sialon and RIP molding conditions of β-Sialon are closely compatible with each other. RIP technology ". 3) “RIP technology for silicon oxynitride ceramics” eliminates cost barriers and allows ceramics to be handled in the same way as steel products. [Selection figure] None |
