A method for producing infrared ZnS domes comprises forming green body by CIP and sintering by hot pressing. In the present invention, the pressure transfers through inert particles hence distributes uniformly while the shape of the dome is controlled by a lower punch head. The ZnS ceramic domes produced by the method of the present invention are of uniform infrared properties with high yield.
