Zinc sulphide is currently being developed as an optical window material for the visible and infrared bands. While this material is adequate for some airborne applications it is evident that a new window material with improved thermal and mechanical properties is required if 8 - 12 pm thermal systems are to be deployed without constraint in all envisaged environmental conditions and scenarios. A little known family of refractory thorium phosphide type cubic and spinel type cubic crystalline rare earth ternary sulphide compounds exists which offers potential for exhibiting better thermal and mechanical properties than ZnS. The crystal chemistry, energy gaps and in some cases melting points of these materials are known but bulk single crystal or polycrystalline samples have not been made to enable their physical properties to be assessed for airborne window applications. Particular compounds are identified for further investigation.
