    • Physical properties
      Antimony has four allotropes. The common allotrope of antimony is a blue-white metalloid. It looks black when powdered. It is brittle, soft, and shiny. Yellow and black antimony are unstable nonmetals. Yellow antimony is only found at very cold temperatures. It is made by oxidation of s…
    • Chemical properties
      Antimony is a rather unreactive element. It does not dissolve in acids easily. It can dissolve in oxidizing acids like nitric or sulfuric acid. It does not corrode easily in air, although the black allotrope can corrode. Antimony burns in air to make antimony trioxide. In excess air, it burns to …

    Antimony(III) oxide is the inorganic compound with the formula Sb2O3. It is the most important commercial compound of antimony. It is found in nature as the minerals valentinite and senarmontite. Like most polymeric oxides, Sb2O3 dissolves in aqueous solutions with hydrolysis. A mixed arsenic-antimony oxide occurs in the nature as the very rare mineral stibioclaudetite.
