摘要： A method of producing a ceramic sintered body having a ceramic membrane which comprises a process of applying a precursor capable of converting into a ceramic membrane having a new function through heating onto at least a portion of a ceramic porous body to impart said function of the surface of the ceramic porous body, a process of applying a precursor capable of converting into a gas-impermeable membrane through heating over the whole surface of the porous body, a process of forming the gas-impermeable membrane by heating, a process of conducting hot isostatic pressing to the porous body, and a process of removing said gas-impermeable membrane. Ceramic sintered bodies having a dense ceramic membrane on the surface can be produced efficiently in very short processes.

摘要： A method for forming a ceramic film comprises the steps of boiling a solution containing ceramics, dipping a base material into the solution, taking the base material out of the solution and drying the base material taken out of the solution in the presence of vapor of said boiling solution. The solution is a solution, in which ceramics is dispersed or dissolved. The solution is a solution, in which a precursor of ceramics is dispersed or dissolved.

摘要： In the method of invention, the formability is imparted to the slurry of a metal or ceramic powder by employing a porous mold and removing the dispersion medium through the evaporation or thermal decomposition thereof, or by using a silazane oil as the dispersion medium and curing it by heating. Since the phase change usually accompanying volume change does not occur in the dispersion medium, strain and deformation rarely occur in the molded body. As result, the sintered body obtained has high dimensional accuracy.

In the .beta.-sialon fine powder obtained by the method of the invention, respective elements of Si, Al, O and N are uniformly distributed in a chemical viewpoint. A high density high strength sintered body can be produced even at a relatively low temperature by using the .beta.-sialon fine powder.
