Abstract : Efforts to prepare new infrared-transmitting ceramic materials and to improve the mechanical properties of existing materials are in progress. Work on new materials is concentrating on phosphides, sulfides, and mixed phosphide/sulfides. Zinc sulfide with submicron grain size has been prepared from organometallic precursors with the hope of improving strength or fracture toughness. A survey of the reaction of hydrogen sulfide with organometallic compounds was conducted to evaluate this route to ceramic sulfides. Keywords: Infrared optical materials. (JHD)
