I have compiled a list of sources for the elements that are available to the amateur chemist. Antimony will be discussed here.    


Antimony is a bluish-gray brittle semimetal. It is insoluble in non-oxidizing acids, but dissolves in oxidizing acids. It burns in air with a bluish flame to produce white antimony trioxide. Antimony is quite toxic, though not as toxic as arsenic. Antimony is found in the earth as stibnite, an antimony sulfide mineral. This is reacted with scrap iron to make antimony metal. When antimony is precipitated from solution, it is a black powder like many metals when precipitated. Antimony strengthens lead and tin alloys.


In element form: Stibnite can be dissolved in concentrated hydrochloric acid and reacted with zinc metal to precipitate amorphous antimony metal. Antimony-tin alloys can be dissolved in HCl, leaving antimony behind. Most lead-acid batteries have antimony alloyed in their electrodes. Pewters generally contain antimony.


In compound form: Some match heads have antimony trisulfide in them.


Here is my sample of antimony. It is powder produced from a pewter alloy in hydrochloric acid.
