Abstract: A high-porosity and high-strength porous silicon nitride body comprises columnar silicon nitride grains and an oxide bond phase containing 2 to 15 wt.%, in terms of oxide based on silicon nitride, of at least one rare earth element, and has an SiO2/(SiO2 + rare earth element oxide) weight ratio of 0.012 to 0.65 and an average pore size of at most 3.5 mu m. The porous silicon nitride body is produced by compacting comprising a silicon nitride powder, 2 to 15 wt.%, in terms of oxide based on silicon nitride, of at least one rare earth element, and an organic binder while controlling the oxygen content and carbon content of said compact; and sintering said compact in an atmosphere comprising nitrogen at 1,650 to 2,200 DEG C to obtain a porous body having a three-dimensionally entangled structure made up of columnar silicon nitride grains and an oxide bond phase, and having an SiO2/(SiO2 + rare earth element oxide) weight ratio of 0.012 to 0.65.

Abstract: A porous metal body having a foam structure of 500 .mu.m or less in average pore diameter, wherein the skeleton is composed of an alloy primaril y including Fe and Cr, and Cr carbide or FeCr carbide is uniformly dispersed i n the texture. The metal porous body is produced by preparing a slurry primarily containing an Fe oxide powder having an average particle diameter of 5 .mu.m or less, at least one powder selected from metallic Cr, Cr alloys , and Cr oxides, a thermosetting resin, and a diluent, applying a coating of this slurry to a resin core body having a foam structure, performing drying, and thereafter, performing firing in a non-oxidizing atmosphere so as to produce a metal porous body having the aforementioned skeleton structure.

Abstract: A ceramics porous body having excellent acid resistance and alkali resistance as well as excellent mechanical strength and durability which can be employed as a filter or a catalytic carrier is provided. A silicon nitride porous body contains a plurality of silicon nitride crystal grains with pores formed in grain boundary parts thereof, or comprises a body part and a pore part so that the body part is formed by a plurality of silicon nitride crystal grains and the pore part forms a three-dimensional network structure. The body part is formed by at least 90 vol. % of silicon nitride crystal grains, which are directly bonded to each other for forming the body part. The porous body which is mainly composed of silicon nitride is brought into contact with an acid and/or an alkali so that a component other than silicon nitride is partially or entirely dissolved and removed, thereby preparing a porous body.

Abstract: A porous metal article which has a foam structure having an average pore diameter of 500 .mu.m or less, has a skeleton comprising an alloy containing Fe and Cr as primary components, and has a structure wherein a carbide of Cr or a carbide of FeCr is uniformly dispersed in the skeleton; a metal composi te material using the porous metal article; and a method for producing the poro us metal article, which comprises preparing a slurry containing an Fe oxide powder having an average particle diameter of 5 .mu.m or less, one or more o f powders of metallic Cr, a Cr alloy and a Cr oxide, a thermoplastic resin and a diluent, as main components, applying the slurry on a resin core having a fo am structure, followed by drying, and then firing the resultant core in a non- oxidizing atmosphere, to thereby form the porous metal article. The porous metal article has excellent heat resistance, and is excellent in strength since the average pore diameter thereof is limited to 500 .mu.m or less, and is useful as a substrate for an electrode, a catalyst carrier and a filter material. A composite material of the porous metal article with an Al alloy or a Mg alloy is excellent in the resistance to abrasion and seizure, and thus useful for various machine parts.

Abstract: A ceramic porous body for a filter or a catalyst carrier, having a structure in which voids each having the same volume as that of a sphere of 10 mu m to 500 mu m in diameter are formed and the voids are communicated with each other through smaller fine pores, the ceramic porous body having a volume fraction of the voids and the fine pores of from 15% to 60% and being formed of components 70% or higher by volume of which is silicon nitride. The ceramic porous body is prepared by mixing coarse silicon nitride powder with fine silicon nitride powder(s) at a mixing ratio by volume of the fine silicon nitride powder to the combined volume of the fine and coarse silicon nitride powders in the range of 1/99 to 1/2; adding one or more compounds of the group IIa elements, the group IIIa elements, transition metals, Al and Si in a range of 1% to 30% by volume as their oxides to the silicon nitride powder mixture; molding the resultant powder mixture; and sintering the molded body in a non-oxidizing atmosphere of at least 0.9 atm at a temperature ranging from 1100 DEG C to 2000 DEG C.
