2 powder (1890°C melting point) having 63-25 μm grain diameter as an auxiliary material, and poly-vinyl acetate and water as a binder. When molten metal is poured at 1550-1600°C casting temperature, the main material in the coating material 2 is melted and the auxiliary material is not melted but included into the main material, and joined with the base material (molten metal). Therefore, on the surface of the casting composed of the solidification of the molten metal, the coated layer, composed of the coating material which is molten and solidified, having the heat-resistance, the oxidizing-resistance and the corrosion-resistance is formed.

摘要： PROBLEM TO BE SOLVED: To obtain a β"-alumina without deviating from stoichiometric ratio by pulverizing a stoichiometrically blended material of Na2 O powder and Al2 O3 powder using a mechanical alloying method to react with each other and next, heat treating the pulverized material at a lower temp. than the conventional. SOLUTION: The Na2 O powder and the Al2 O3 powder are blended to become stoichiometric ratio, the blended material is sufficiently pulverized until the reaction of the Na2 O with Al2 O3 occurs with a hard ball (e.g. zirconia ball) to react with each other. The resultant pulverized material is heated under the atmosphere at 500-800 deg.C for a prescribed time to be crystallized. Since the mechanical alloying method used for the production of the β"-alumina is a method for mechanically mixing and pulverizing poor components to react with the powder components each other, the structural components of the β"- alumina are allowed to react with each other by mixing in stoichiometric ratio without using a carbonic acid compound. Then, since the crystallization at a low temp. is enabled, the deviation of stoichiometric ratio caused by the evaporation of Na or the like is prevented.

摘要： PURPOSE:To form an electrode membrane having optional thickness even if the membrane is dense by adding a thermoplastic resin having good molding capability to electrode material powder, kneading to form a uniform mixture, heating the mixture to give it fluidity, then pressing the fluid mixture into a mold frame. CONSTITUTION:A mold frame 2 for molding a fuel electrode 1 is mounted to the outside of a porous base pipe 9, and the mold frame 2 is heated with a band heater 7 to keep the fluidity of an electrode material mixture. A thermoplastic resin is added to fuel electrode material powder, and they are sufficiently mixed with a kneader, then the kneaded mixture is supplied to a pressure chamber 6. The pressure chamber 6 is connected to a raw material supply part 8 of the mold frame 2, then the fluid mixture is supplied into the mold frame 2 under pressure. The fuel electrode 1 is cooled and solidified, then the electrode is taken out by dividing the mold frame 2. After unnecessary part formed in the raw material supply part 8 is removed, the electrode is put in a heating furnace. The fuel electrode 1 is heated so as to keep its shape in the furnace, and the thermoplastic resin is removed by decomposition and vaporization. The electrode 1 is heated to sintering temperature and the electrode material powder is sintered.

摘要： PROBLEM TO BE SOLVED: To provide a method and device for testing strength of ceramic tube by which a correct strength-measured result can be obtained from a ceramic tube, by preventing the occurrence of local breakage in the vicinity of the opening of the ceramic tube and reducing the number of strength unmeasurable portions as much as possible. SOLUTION: At the time of measuring the fracture strength of the ceramic tube by imparting an internal pressure to the ceramic tube by supplying a pressure fluid into a flexible tube inserted into the ceramic tube, a cylindrical skirt ring is inserted into the ceramic tube to the distance of L0 =2×(r×t) (wherein, (r) and (t) respectively denote the inside diameter and wall thickness of the opening of the ceramic tube) from the end face of the opening between the inner periphery of the opening of the ceramic tube and the outer periphery of the flexible tube. Then the fracture strength of the ceramic tube is measured by supplying the pressure fluid into the flexible tube.
