Abstract

Catalysts are precipitated in porous meal bodies which have been formed by metallizing a non-metallic lattice core and sintering the metallized structure; the lattice core may remain in the body or may be decomposed or eliminated before or during the sintering process which may take place in an inert or reducing atmosphere and under pressure. Several cores, of similar or dissimilar composition and structure, may be sintered together and the core or body may be shaped before, during or after sintering. Metallization may be by vapour deposition, dipping or electro deposition or by vapour deposition followed by electro deposition; the core may be a close or loose fabric of glass, synthetic fibres or textile threads; decomposable metallic compounds may be introduced into the core or skeleton before, during or after sintering, e.g. nickel, carbonyl may be introduced to form nickel.ALSO:Porous metal bodies are formed by metallizing a non-metallic lattice core and sintering the metallized structure; the lattice core may remain in the body or may be decomposed or eliminated before or during the sintering process which may take place in an inert or reducing atmosphere and under pressure. Several cores, of similar or dissimilar composition and structure, may be sintered together and the core or body may be shaped before, during or after sintering. Metallization may be by vapour deposition, dipping or electrodeposition or by vapour deposition followed by electro deposition; the core may be a close or loose fabric of glass, synthetic fibres or textile threads; decomposable metallic compounds may be introduced into the core or skeleton before, during or after sintering e.g. nickel carbonyl may be introduced to form nickel. By introducing alloys into the core, a sliding bearing material may be formed or, if the metallizing metal is a bearing alloy, oil may be introduced to form a self-lubricating bearing material; magnetic bodies may be formed by filling the interstices with suitable metals or alloys; catalysts may be formed by precipitation reactions within the bodies; or accumulator plates may be formed when the metal is nickel by treatment with nitric acid and conversion of the nitrate to hydroxide.
