Abstract:
A process for depositing at least one source metal onto at least one receiving metal on a substrate, comprising the steps of;(a) placing said substrate containing said at least one receiving metal in a chamber containing said source metal and an activator;(b) heating said chamber and its contents in a non-oxidizing environment at a temperature in the range from between about 700.degree. C. to about 1,000.degree. C., for a period of time ranging to a maximum of about 200 minutes; and(c) allowing said chamber and its contents to cool so that said receiving metal has at least one layer of said source metal adhered thereto, wherein the improvement comprises: bonding said source metal to at least one sheet of porous inert material, thereby forming a tile, and placing said tile of porous inert material in proximity to said receiving metal such that said source metal is separated from said receiving metal by said sheet of inert material, whereby a gaseous compound containing said source metal passes through said sheet of porous inert material to said receiving metal and deposits said source metal on said receiving metal.
