Abstract:
Composite materials on the basis of powders of platinum metals with designated grain size and grain fineness are demanded by the electronic component base (ECB) of modern radio electronics. From the analytical probes executed in work follows that two new technologies of their receiving meet to the requirements imposed to powders of platinum metals: method of magnetic separation and technology of a karbonilization. The last is described in detail. It represents realization of the reactions weeping at impact of monoxide of carbon on solutions of platinum metals chlorine complexes. Features of receiving various parties of powders of palladium in the course of realization of hydrocarbonyl processes in the specialized reactor and also their main properties are described. From the point of view of industrial production of powders of palladium, the hydrocarbonyl mode as showed results of the executed probes, is characterized by high purity of metals and low cost of production. Taking into account that by the industry is issued palladozamin Pd(NH3)2Cl), it is possible to conclude that the mass production of powders of palladium with the necessary physical and chemical technological properties won't have technical difficulties in its realization.
