| 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. |
