The metallurgy of antimony

2012-7-17 · 1. Background. Antimony is a silvery, white, brittle, crystalline solid that exhibits poor conductivity of electricity and heat. It has an atomic number of 51, an atomic weight of 122 and a density of 6.697 kg/m 3 at 26 °C. Antimony metal, also known as ''regulus'', melts at 630 °C and boils at 1380 °C.Antimony and the natural sulfide of antimony were known as early as 4000 BC.
