    摘要: A method of manufacturing an electrically conductive cermet that includes less than 35% by volume of a precious metal by mixing a powdered refractory ceramic with the powdered metal, molding the mixture into a green, and sintering the green to create a cermet with a dense ceramic phase and a metallic phase in the form of a coherent network. The object is good electric conductivity at a low metal content. The precious metal powder is selected to shrink less and exhibits less sintering tendency as it forms the metallic phase than does the ceramic powder as it forms the ceramic phase.

    摘要: A process for making a crystalline solid-solution powder which involves reacting at least two reactants in a plasma arc of a plasma chamber and blast-cooling the resultant product in a high velocity gas stream to form the powder. The first reactant is a molten metal alloy and the second reactant is a gas. The reaction is carried out in a plasma arc and the products rapidly cooled by a gas stream acting at the outlet opening of the plasma chamber. The crystalline solid-solution powder formed by the process has a low electrical resistivity. If an indium-tin alloy is used as the first reactant and oxygen as the second reactant, there is obtained an indium-tin-oxide (ITO) crystalline solid-solution powder which, when compacted to 40% of its theoretical density, has an electrical resistivity in the range of about 2 .OMEGA.cm. This ITO crystalline solid-solution powder is particularly suitable for preparing an ITO target, with high electrical conductivity and thus high achievable sputtering rates.

    摘要: The targets for cathodic sputtering according to this invention are formed of hot-pressed or hot isostatic-pressed indium oxide/tin oxide powder with a minimum density of 95% of the theoretical density and with a sub-stoichiometric oxygen content are known. In order to provide the improvement of high stability and, simultaneously, high sputtering rate, it is proposed according to the invention that the target have a crystalline phase which is formed as a solid solution of indium oxide and tin oxide with a minimum of 90% by weight, preferably a minimum of 97%, of the solid solution, and which has an average grain size ranging from 2 .mu.m to 20 .mu.m. In order to make available a simple and cost-efficient method for producing a target consisting of a starting powder of indium oxide/tin oxide, which allows for a precise setting of the oxygen content and a homogeneous chemical composition throughout the entire target volume, it is proposed that a starting powder be used that is produced by oxidizing finely distributed indium tin metal.
