Thallium Oxide
Thallium has several oxides: *Thallium(I) oxide Tl2O *Thallium(III) oxide Thallium(III) oxide, also known as thallic 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 w ...

Thallium(I) Oxide
Thallium(I) oxide is the inorganic compound of thallium and oxygen with the formula Tl2O in which thallium is in its +1 oxidation state. It is black and produces a basic yellow solution of thallium(I) hydroxide (TlOH) when dissolved in water. It is formed by heating solid TlOH or Tl2CO3 in the absence of air. Thallium oxide is used to make special high refractive index glass. Thallium oxide is a component of several high temperature superconductors. Thallium(I) oxide reacts with acids to make thallium(I) salts. Tl2O adopts the anti-cadmium iodide structure in the solid state. In this way, the Tl(I) centers are pyramidal and the oxide centers are octahedral. Thallium(I) oxide, like all thallium compounds, is highly toxic. Preparation Thallium(I) oxide can be produced by decomposition of thallium(I) hydroxide at 100 °C or by heating thallium(III) oxide Thallium(III) oxide, also known as thallic oxide, is a chemical compound of thallium and oxygen. It occurs in natu ...
