A native element; antimony metal is extracted from stibnite ore and other minerals. Used as a hardening alloy for lead, especially storage batteries and cable sheaths; also used in bearing metal, type metal, solder, collapsible tubes and foil, sheet and pipes and semiconductor technology.auxite ore is the main source of aluminum and must be imported from Jamaica, Guinea, Brazil, Guyana, etc. Used in transportation (automobiles), packaging, building/construction, electrical, machinery and other uses.

It is generally known that a metal film cannot be bonded to a ceramic substrate unless oxygen is present; that is, without oxygen, generally present as the metal oxide, there can be no eutectic process. Likewise, copper cannot wet a ceramic of aluminum nitride unless some form of oxygen is present.hus the copper film is bonded to a substrate of Al 2 O 3 which is grown on the surface of the aluminum nitride substrate. The Toshiba and Mitsubishi research, however, is unsuitable for the purposes for which the instant invention is required.
