Summary

New ceramic composites for far infrared window materials have been developed, based on diamond toughened zinc sulfide. The diamond particulate strengthened composites show improved toughness while retaining good infrared transmission. The optical properties depend strongly on the green state processing of the ZnS and diamond powders and on the hot-pressing conditions. Correlation between processing variables and the optical and mechanical properties will be discussed.
