Abstract: This invention relates to sintered, substantially glass-free, ceramic bodies, and more particularly to an improved method of producing a metallized surface on such ceramic bodies. The method includes coating a sintered ceramic body with a metallizing ink composition containing a metal from the group molybdenum, tungsten, and mixtures of each of such metals with manganese, and subsequently firing the coated ceramic body in a wet reducing atmosphere to oxidize the metal from said first-mentioned group to yield a metallic layer which is tightly bonded to the surface of the ceramic body. The oxide of the metal from said firstmentioned group bonds directly to the ceramic body which in turn mechanically adheres the metal layer, from said second-mentioned group, to the ceramic body.
