Abstract: A new technique for forming non-rectifying electrical contacts to III-V semiconductor materials, without the use of dopants or of an alloying procedure, is disclosed. In accordance with this technique, an electrical contact is formed simply by depositing a region of material (onto the semiconductor material) having a composition which includes at least one metal element and at least one of three specific Group V elements, i.e., P, As, or Sb, and having a bulk electrical resistivity equal to or less than about 250 .mu..OMEGA.-cm. Alternatively, a contact is formed by depositing nickel, or a nickel-containing material essentially free of gold and silver, and having a composition which does not include any of the three Group V elements. The nickel, or nickel-containing material, is then reacted with the substrate to form a compound having a composition which includes nickel as well as one of the three Group V elements.

Abstract: A method of producing III-V materials by reducing a complex salt in a hydrogen atmosphere is shown. For example, complex salts reduce to InP or GaAs. The salts are conveniently prepared by coprecipitation from a salt solution or by other methods. The stoichiometry can be modified by applying an overpressure of the more volatile element or elements during reduction.

Abstract: In the process of producing metal alloy parts by the reduction of powder metal oxide compacts, it has been discovered that single phase alloy parts may be produced by an agglomerated mixture of metal oxides without a separate annealing step. The metal oxide mixture is formed into agglomerates by spray drying a solution of metal salts which are subsequently decomposed, or other techniques, compacted to the desired shape, and then reduced in a hydrogen atmosphere at high temperature. In the case of alloys that would otherwise segregate, a quenching step follows the reduction of the metal oxide shape. As only oxides are involved prior to reduction, problems with surface oxidation are avoided. A sintering step in air can be used to give the oxide compact structural integrity before reduction.

Abstract: A novel method of producing mixed metal oxide powder (e.g., ferrite powder, or high temperature superconductor powder such as YBa.sub.2 Cu.sub.3 O.sub.x powder) is disclosed. The method comprises forming an intimate mixture of appropriate metal salts (e.g., nitrates and acetates), at least one of which is an oxidizing agent with respect to at least one of the others, and heating the mixture to a reaction temperature such that an exothermic redox reaction occurs. Appropriate choice of oxidizing and reducing agents permits control of heat of reaction and reaction temperature. The product of the reaction typically is a precursor of the desired mixed oxide, the precursor typically consisting essentially of the metal constituents of the mixed oxide and oxygen. Heat treatment in an O.sub.2 -containing atmosphere transforms the precursor into the desired mixed oxide powder. The thus produced powder can then be used in conventional fashion, e.g., to produce bodies therefrom by pressing and/or sintering.
