Upon being brought into contact with each other, {alpha}-Cu{sub 2}Se and {alpha}-CuSe pellets reacted entirely forming Cu{sub 3}Se{sub 2} at room temperature. After 10 days, the reaction was almost completed. Weight measurements revealed that copper atoms migrated from {alpha}-Cu{sub 2}Se to {alpha}-CuSe. Solid-state reactions were also observed in the ({alpha}-Cu{sub 2}Se+Cu{sub 3}Se{sub 2}) and ({alpha}-Cu{sub 2}Se+CuS) systems, but not in the (Cu{sub 3}Se{sub 2}+{alpha}-CuSe) (Cu{sub 2}S+CuS) and ({alpha}-CuSe+Cu{sub 2}S) systems. Therefore, the high ionic conductivity of copper ions in {alpha}- and {beta}-Cu{sub 2}Se is considered to be responsible for the solid-state reactions observed in these systems.
