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.
