Antimony (Sb) - Chemical properties, Health and Environmental …

Antimony and some of its alloys expand on cooling. Antimony has been known since ancient times. It is sometimes found free in nature, but is usually obtained from the ores stibnite (Sb 2 S 3) and valentinite (Sb 2 O 3). Nicolas Lémery, a French chemist, was the first person to scientifically study antimony and its compounds.
