Thallium(III) oxide

Thallium(III) oxide is a chemical compound of thallium and oxygen.It occurs in nature as the rare mineral avicennite. [3] Its structure is related to that of Mn 2 O 3 which has a bixbyite like structure. Tl 2 O 3 is metallic with high conductivity and is a degenerate n-type semiconductor which may have potential use in solar cells. [4] A method of producing Tl 2 O 3 by MOCVD is known. [5]

In the initial samples and in the products of their acid treatment, some ultramicroscopic inclusions of molybdenite, thallium oxide and chlorite, and tellurium oxide were found. The origin of the molybdenite is supposedly related to the sedimentation of organic matter particles from oceanic water, thus, forming a local reducing environment.

Thallium(III) oxide, Tl 2 O 3, is a black solid which decomposes above 800 °C, forming the thallium(I) oxide and oxygen. The simplest possible thallium compound, thallane (TlH 3 ), is too unstable to exist in bulk, both due to the instability of the +3 oxidation state as well as poor overlap of the valence 6s and 6p orbitals of thallium with ...
