Antimony The Canadian Encyclopedia
2006-2-6 Antimony (Sb) is a silvery-white, lustrous, crystalline solid. Uncharacteristically for metals, it is brittle and conducts heat and electricity poorly. Antimony melts at 630°C and boils at 1380°C. The mineral stibnite is the most important source of antimony. Antimony is also recovered as a by-product of nonferrous metal production.
