ABSTRACT:
This invention relates to a metallizing composition capable of forming an electroconductive coating of satisfactory adherence properties on the surface of a sintered ceramic article, particularly on a sintered silicon nitride type ceramic article. The metallizing composition contains metal salts of tungstic acid and/or molybdic acid and a metal of Group IVb of the Periodic Table of Elements or a compound thereof. The electroconductive coating of high adherence properties is formed by applying the metallizing composition on a sintered ceramic article and drying the deposited layer of the composition in air, heating the dried layer, and firing the layer in a non-oxidizing atmosphere. The metallizing composition is suitable for the formation of the electroconductive coating on a complexly shaped sintered ceramic article such as, for example, on the inner surface of a hollow ceramic article.
