Abstract
The hardness of zinc sulfide is increased by adding selective elements within a specified range to the crystal lattice of the zinc sulfide. The increased hardness over conventional zinc sulfide does not substantially compromise the optical properties of the zinc sulfide. The zinc sulfide may be used as a protective coating for windows and domes.
