The study of influence of structural inhomogenities upon optical parameters of zinc sulphide optical ceramic

摘要

The aim of present paper was to find out the influence of structural inhomogenities upon the main parameter of optical ceramic obtained from zinc sulphide by hot pressing, IR transmission. It is directly influenced of microstructure characteristics of ceramic material. Microstructure of studied optical ceramic from zinc sulphide is influenced by starting powder parameters (purity, particle size distribution, stoechiometry) and processing conditions. Taking into account the experimental results we tried to relate transmission and microstructure, the last one being function of pressure, temperature, time, particle size distribution and purity.
