Lanthanum(III) telluride is an inorganic compound, one of the tellurides of lanthanum, with the chemical formula La₂Te₃. Lanthanum(III) telluride is prepared by oxidizing a mixture of lanthanum, tellurium and sodium carbonate at 400 °C.^[1] There are also literature reports on preparing lanthanum(III) telluride using lanthanum(III) chloride and tellurium as raw materials. In the reaction, tellurium is first oxidized to +4 oxidation state, and then hydrazine hydrate is reduced to −2.^[2] Various phases such as CuLaTe₂ and Cu₄La₂Te₅ can be formed in the La₂Te₃-Cu₂Te system.^[3]
