Abstract: Glycerol is used as a solvent medium for the precipitation of a complex of nickel and glycerol material. The precipitate is separated from the liquid solvent and dried and calcined in air to produce small (nanometer size) particles characterized by a nickel core encased in a nickel oxide shell. The proportions of nickel core and nickel oxide shell can be controlled by management of the time and temperature of heating in air. Prolonged heating in air can produce nickel oxide particles, or calcining of the precipitate in nitrogen produces nickel particles.

Abstract: A method for treating a porous item constructed of metal powder, such as a powder made of Series 400 stainless steel, involves a step of preheating the porous item to a temperature of between about 700 and 900° C. degrees in an oxidizing atmosphere and then sintering the body in an inert or reducing atmosphere at a temperature which is slightly below the melting temperature of the metal which comprises the porous item. The thermal stability of the resulting item is enhanced by this method so that the item retains its porosity and metallic characteristics, such as ductility, at higher (e.g. near-melting) temperatures.
