Abstract

A non-metallic surface is covered with copper particles having a diameter not exceeding 70m and substantially all greater than 1m by coating with a slurry of the particles in an inert volatile liquid, the copper particles being coated with silver, gold or platinum. Specifications 672,255, [Group XXXVI], 672,260 and 690,486, [both in Group II], are referred to.ALSO:Copper powder of a size not exceeding 70m but substantially all particles exceeding 1m is uniformly coated with a noble metal (i.e. silver, gold or platinum). The coating may be applied by chemical decomposition or electroplating, examples being given. The powder may be applied as a slurry in an inert volatile liquid such as acetone and applied to the surface of an organic electrically insulating material, heat and pressure being applied to the resulting coated surface to form printed circuits (see Specifications 672,255, [Group XXXVI], and 690,486). Resistors may be made as disclosed in Specification 672,260. The slurry may be applied to the surface of an article which does not soften under the influence of heat and pressure by applying the slurry before completely condensing the resin. The powder may be applied with the aid of an adhesive. It is stated that copper powder can be prepared by the reduction of copper oxide with protalbinic acid and an ethanolamine.
