A process for producing a thermal-resistant ceramic fired body is disclos As an additive for ceramic powder is used at least one specified organosilicon polymer selected from the group consisting of [I] organopolysiloxanes, [II] organosiloxane copolymers, [III] polycarbosiloxanes and [IV] nitrogen-containing organosilicon polymers.

Process for producing a thermal-resistant ceramic fired body

Metal nitride sintered moldings are produced by mixing metal nitride powders with an organosilicon compound or an organosilicon high molecular weight compound as a binder, molding the mixture into a desired shape and heating the formed molding under a non-oxidizing atmosphere to sinter the metal nitride powders.

Method for producing metal nitride sintered moldings

A heat-resistant composite material reinforced with continuous silicon carbide fibers is produced by forming a powdery ceramics matrix and the fibers into a composite, and pressing and heating the composite into a sintered composite. The composite material is excellent in the mechanical strength at a high temperature, heat resistance, oxidation resistance and corrosion resistance.

Method for producing heat-resistant composite materials reinforced with

Cobalt or cobalt alloy composite materials reinforced with continuous silicon carbide fibers, which have a high tensile strength, a low elongation, a high Young modulus and a high tensile strength at a high temperature, are produced by filling spaces in piles of the continuous silicon carbide fibers containing 0.01%-30% by weight of free carbon with melted or powdery metallic cobalt or cobalt alloy and integrating the said fibers with the said metal.

Cobalt or cobalt alloy composite materials reinforced with continuous

Light metal composite materials reinforced with novel continuous silicon carbide fibers composed of aluminum, aluminum alloy or magnesium alloy matrix and the continuous silicon carbide fibers containing 0.01-40% by weight of free carbon, in which the free carbon is reacted with aluminum or added metal elements in the aluminum alloy or magnesium alloy to form carbides. When the silicon carbide fibers are coated with a metal or ceramics, the wettability of the silicon carbide fibers to said matrix is more improved.

Heat resistant and super hard composite materials are produced by mixing more than 60% by weight of an organosilicon high molecular weight compound, the main skeleton components of which are silicon and carbon or an organosilicon high molecular weight compound, the main skeleton components of which are silicon and carbon and which contains foreign elements other than silicon, carbon, hydrogen and oxygen with not less than 40% by weight of metal material powders consisting mainly of at least one metal element, molding the mixture into a shaped article and baking the shaped article under a non-oxidizing atmosphere at a temperature of lower than the semi-melting point of the above described metal powders.

A hydrogen-occluding alloy consisting of at least one element selected from rare-earth elements R and magnesium or of at least one element selected from rare-earth elements R, magnesium and nickel has a small density and is inexpensive and has an excellent hydrogen occlusion capacity as compared with the conventional La-Ni series alloys. The R-Mg series alloys and R-Ni-Mg series alloys are suitable as a material for hydrogen container.
