摘要： PROBLEM TO BE SOLVED: To provide a manufacturing method of an alumina ceramic sintered compact having high strength, good thermal and chemical stability, and excellent insulation property, corrosion resistance, and wear resistance, and to provide the alumina ceramic sintered compact having high strength. SOLUTION: In the manufacturing method of the alumina ceramic sintered compact, raw material powder is dispersed in a solvent by a non-pulverizing medium type mill treatment to be made slurry, a molded body is obtained with the slurry by casting molding, and next, the molded body is fired. The alumina ceramic sintered compact is obtained by this method. The non-pulverizing medium type mill treatment is, for example, a system which makes a high-pressure and high-speed slurry stream collide with each other or makes it collide with a fixed wall.

摘要： PROBLEM TO BE SOLVED: To provide a ceramics green sheet and a method of producing the same. SOLUTION: In the production method of the ceramics green sheet using a ceramics slurry containing at least an organic binding agent, a solvent, a surfactant/dispersant and raw material ceramics, an aqueous solvent is used as the solvent, and a uniform dispersion slurry obtained by using a raw ceramics containing particles with an average particle diameter of at most 100 nm as the above ceramics material is tape-molded and dried to form a tape molding. The ceramics green sheet and the part material of the ceramics sheet are produced by the above method, and then the high quality ceramics green sheet and the part material can be provided by using a ceramics powder of nano sizes as a raw material.
