Precipitation Hardening of Infrared Transmitting ZnS Ceramics

Abstract

Precipitation strengthening is a potentially attractive technique for hardening and toughening infrared transmitting materials. The controlled precipitation of a finely dispersed second phase offers the opportunity to improve mechanical properties without degrading optical properties. It is well established that the presence of an appropriate dispersion of second phase particles can improve the mechanical behavior of ceramics, and, by maintaining a particle size < 100 nm, scattering losses in the infrared will be circumvented
