Copper telluride is a black crystalline powder that is stable in air at room temperature. Copper telluride is not only an important inorganic material, but also an excellent form of storage for telluride and copper resources. Cu telluride was generated by replacing Te with Cu in H2SO4 solution, resulting in the separation and considerable enrichment of telluride from many metal ions.
Cu displaces Te, which can have either + 4 or + 6 valence to produce Cu2 Te, which is not affected by tellurium valence. In the presence of oxidants, copper telluride can react with acids or bases, which is the basis for the separation and recovery of Cu and Te. In short, tellurium is characteristic of recovering tellurium from solution by combining tellurium with copper at higher temperatures.
Ecological data of copper telluride:
This substance may be hazardous to the environment and special attention should be paid to water bodies.
