IPC: C04B33/13
Filed: 1995-05-12
Abstract: PURPOSE: To obtain a body for pottery free from the remaining of a black core caused by firing by mixing a material to be reacted with carbon in firing process to the body for pottery containing an organic material. CONSTITUTION: In this body for pottery containing carbon or the organic material producing carbon by thermal decomposition in firing process, the body is mixed with the material capable of removing or reducing the carbon by being reacted with the carbon in firing process. The material capable of removing or reducing the carbon in preferably a calcium compound, nitrate compound or these mixture. It is thought that the oxygen produced by the thermal decomposition of the material is reacted with the carbon to produce CO or CO2 , which is discharged from the fine pores in the body. It is estimated that gypsum (CaSO4 +2H2 O), for example, is decomposed into CaSO4 and 2H2 O at the early time of the firing to disperse H2 O, and the reaction of CaSO4 +2C=CaS+2CO2 is caused by further heating to remove the carbon.

Filed: 1988-06-07
Abstract: PURPOSE:To form a thin good-quality film at high speed by providing an electric discharge space in an electric discharge electrode and also providing a hollow cathode electric discharge part to a gas injection hole in the electric discharge electrode in a glow discharge CVD equipment so as to prevent the generation of pulverized powder. CONSTITUTION:In a equipment for forming a thin film on the surface of a base material 100 set in a manner to be opposed to an electric discharge electrode 21 by a glow discharge CVD method, a glow discharge space 22 is formed in an electrode having a duplex structure consisting of an electric discharge electrode 21 and a ground electrode 24. Further, a gas injection hole 28 in the direction of the base material is provided to the electrode 21 on the base material 100 side, and a hollow cathode electric discharge part 27 is provided to the above hole 28. Then, glow discharge is initiated in the space 22, and active species generated in the space 22 are transferred through the injection hole 28 to the base material 100 to form a film. Since the lives of the active species are short in the above state and film- forming velocity is decreased, gas decomposition efficiency is improved by means of hollow cathode electric discharge in the electric discharge part 27. Moreover, since the plasma production part (space 22) can be separated from the base material 100, plasma can be produced with high high-frequency power with no fear of causing deterioration in film quality due to plasma damage, and gas decomposition efficiency can be improved.
