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.

Aluminium nitride is stable at high temperatures in inert atmospheres and melts at 2800 Â°C. In a vacuum, AlN decomposes at ~1800 Â°C. In the air, surface oxidation occurs above 700 Â°C, and even at room temperature, surface oxide layers of 5-10 nm have been detected.he material dissolves slowly in mineral acids through grain boundary attack, and in strong alkalies through attack on the aluminium nitride grains. The material hydrolyzes slowly in water. Aluminium nitride is resistant to attack from most molten salts, including chlorides and cryolite.
