Antimony is a member of group 15 of the periodic table, one of the elements called pnictogens, and has an electronegativity of 2.05. In accordance with periodic trends, it is more electronegative than tin or bismuth, and less electronegative than tellurium or arsenic.Antimony is stable in air at room temperature, but reacts with oxygen if heated to produce antimony trioxide, Sb 2 O 3.
United States Antimony Corporation (USAC) NYSE (uamy) is a rapidly growing natural resource company that is increasing its raw material supply of antimony from properties in Mexico and third parties around the world. USAC has produced various antimony products since 1969 and is a fully integrated mining, transportation, milling, smelting, and selling company. USAC operates … Home …
