Abstract
Abstract This invention relates to nitrides, oxides, arsenides, borides, phosphides, tellurides, titanates, silicides, carbides, etc. of metals or metalloids, such as or in their compacted forms, as substrates or base elements. These can be readily joined with various other substrates employing as a coating, film, layer or interlayer former a tin, lead, indium, or alloys thereof, in an admixture with a carbide or carbonyl former and joining the substrate or base in a carbon monoxide atmosphere with the coating, etc. former.
