Title: Production of ceramic parts
Inventor: MATSUOKA HIROSHI
IPC: B28B1/00
Filed: 1991-05-23
Abstract: PURPOSE:To obtain a method for producing ceramic parts wherein even the complex shape of a hollow part can be extremely easily formed and a ceramic sintered body having a good inner wall surface and high strength is formed. CONSTITUTION:In a method for producing ceramic parts, a core 4 formed of the material having high thermal expansion coefficient and low m.p. is used and a compact 5 of ceramic powder is formed. This compact 5 of ceramic powder is arranged in a carbon mold 6. Since the core 4 is once thermally expanded by temp. rise, the inner wall surface of the compact 5 is exerted with compressive force by thermal expansion of the core 4. The vicinity of the inner wall surface of the hollow part of the compact 5 is compressed and formed into a dense structure and also strength is raised because the compressive force is previously exerted. Thereafter the temp. is furthermore raised to melt the core 4. This core 4 is removed from the hollow part of the compact 5 of ceramic powder. Even the complex shape of the hollow part can be extremely easily formed.
