Thallium(III) oxide is a chemical compound of thallium and oxygen. It occurs in nature as the rare mineral avicennite. Its structure is related to that of Mn2O3 which has a bixbyite like structure. Tl2O3 is metallic with high conductivity and is a degenerate n-type semiconductor which may have potential use in solar cells. A method of producing Tl2O3 by MOCVD is known.Any practical use of thallium(III) oxide will always have to take account of thallium's poisonous nature. Conditions/substances to avoid are: moisture and acids.
