Crucial requirements for missile windows and domes include (i) excellent infrared transmission, (ii) ability to withstand extraordinary mechanical, thermal stresses and (iii) harsh environmental conditions. Multi-spectral ZnS has high transparency in a wide spectral range (0.4 m to 12 m). It is the material of choice for long wave-infrared and semi-active laser domes. The current method of preparation typically uses Chemical Vapor Deposition (CVD). However ZnS CVD has relatively low hardness which limits its use especially for air-borne military systems where particle or rain erosion may occur. A sintered compact powder by hot pressing nanoparticles prepared through a green process will eliminate the use of toxic chemicals and decrease the cost of ZnS while improving its mechanical and optical properties. During the Phase I project Lynntech developed a low temperature, green process for production of ZnS nanoparticles. This process is easily scalable and its simplicity will have an impact on the final goal cost of $500/kg of ZnS will be achieved. The goal of the Phase II project will be to demonstrate synthesis rates between 2-10 kg of nanopowder material on a daily basis with emphasis on purity (99.99%) and uniform size distribution.
