Paper Abstract

The development of infrared-transmitting ZnS-based ceramics with a combination of high strength, hardness and toughness over a range of temperatures is highly desirable. The approach we are currently pursuing is a familiar one to metallurgists, namely the exploitation of thermal, and possibly mechanical, processing of ZnS-base "alloys". Knowledge of the phase equilibria of various ZnS-rich systems is essential to achieve our objectives. Unfortunately, the literature on this subject is sparse, and we have had to undertake such investigations ourselves. This paper describes the results of our initial studies of the solid-state phase equilibria in the ZnS-CdS and ZnS-Ga2S3 phase diagrams. We also discuss possible processing routes to achieve hard and tough ceramics utilizing the phase diagrams established.
