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.

The Al-O bonds have a percent ionic character of 57%. They are, of course, 43% covalent. You see, all bonds lie along a continuum between ionic and covalent, and while it is possible to have a 100% covalent bond, it is impossible to have a 100% ionic bond.All bonds result in the sharing of electrons, and all bonds are covalent.But some covalent bonds are very, very polar and it is these really polar bonds that we call ionic, simply because they have a high ionic character, not because there are actual ions in the solid state.est Answer: Aluminum oxide, like many solid substances, exists as a network of atoms, in the case Al and O. There are no molecules of Al2O3, Take a look: http://upload.wikimedia.org/wikipedia/co...
