Abstract:

The aim of the research conducted as part of the project was to develop a composite for the production of conductive layers on elements of electric power contacts by thermal silvering with the addition of ultrafine copper particles, copper oxide or copper particles coated with silver. The document will focus on the production of silver coated copper powder. First the copper powder with the assumed parameters such as: particle size distribution, shape, purity was produced using chemical method. Then, the silvering of copper particles was carried out by means of a chemical method, using silver nitrate as the silver precursor. The following silver | copper molar ratios were used during the process: 0.1 | 1M; 0.6 | 1M; 1|1 M. The produced powders were analysed for specific surface area, phase composition, particle size distribution, morphology, layer appearance, chemical composition.
