Cupric telluride, CuTe

The Cupric telluride, CuTe is stated to be formed by the action of tellurium-powder on a solution of cupric acetate in presence of sulphur dioxide. It can also be precipitated from a solution of sodium telluride, Na₂Te; a sesquitelluride, Cu₂Te₃, is obtained similarly from the polytelluride Na₄Te₃. A telluride of the formula Cu₄Te₃ occurs as the mineral rickardite.
