摘要： PROBLEM TO BE SOLVED: To provide a heating implement for a microwave oven, which is easily manufactured, capable of exhibiting sufficient strength, and excellent in heat generation and heat insulating performance.
SOLUTION: A ceramic sintered body is put into a furnace, and LP gas is fed to perform the carburizing process under high-temperature environment. Then, carbon is deposited on the surface of the ceramic sintered body and into pores constituting a porous structure to form a carbon thin-film layer. The ceramic sintered body with this carbon thin-film layer makes the heating implement for the microwave oven.

摘要： PURPOSE:To easily obtain the porous ceramics which is high in porosity and sharp in pore size distribution by utilizing a soln. which is gelatinized by a chemical reaction or heating as a molding method for obtaining the porous ceramics. CONSTITUTION:A slurry prepd. by dispersing ceramics raw materials into the org. high-polymer soln. which is gelatinized by the chemical reaction or heating is prepd. at the time of forming the porous ceramics by molding the ceramics raw materials to granular, fiber, pipe, sheet, film or other shapes and calcining the molding. This slurry is gelatinized by introducing the slurry into a soln. in which an acid or cation of bivalent or higher valency exists or by heating the soln. The porous ceramics which has the uniform structure of the high porosity and high strength and does not change the porous characteristic at a high temp. is extremely easily produced. The material, the soln. of which is gelatinized by the chemical reaction is adequately sodium alginate, ammonium alginate, etc.

摘要： PROBLEM TO BE SOLVED: To obtain a low-cost deflocculant for a slurry excellent in dispersibility and preservability by using a zeolite having monovalent cation releasing ability. SOLUTION: A slurry used in ceramic molding is prepared by using a ceramic material of 0.01-500 μm average particle diameter such as porcelain clay, kaolin feldspar, silica, powder of potsherd, alumina, sericite or talc, a solvent such as water, and a zeolite of 0.01-500 μm average particle diameter having monovalent cation releasing ability as a deflocculant. The amount of the zeolite is 0.01-20 wt.% of the amount of the ceramic material. The concentration of the ceramic material is appropriately about 50-85 wt.%. Since the deflocculant for the slurry releases monovalent cations that contribute to dispersibility in the solvent or adsorbs or ion-exchanges multivalent cations that hinder dispersion while releasing monovalent cations, the ceramic powder is efficiently dispersed in the slurry. The deflocculant is excellent also in work efficiency, and steps after the preparation of the slurry are shortened.
