Abstract
Compositional gradients in a body of mercury cadmium telluride are removed by heat treating the mercury cadmium telluride in a closed container at a temperature which is less than the solidus temperature. The constituent vapor pressure within the closed container is maintained at a value which is lower than the equivalent vapor pressure of the constituents of the mercury cadmium telluride body.
