Abstract: The transmittance of CVDZnS before and after heat isostatic processing (HIP)was measured. X-ray diffraction, AEM and metaloscopy were adopted to study the microstructure
of stereotype and HIP processed CVDZnS. Based on the different microstructures of CVDZnS before and after HIP observed,the reasons why the transmittance of CVDZnS
can be improved after HIP processing was analysised. The results show that the grain size of CVDZnS is improved dramatically after HIP processing,and the defects
formed during the growth of CVDZnS are minimized, so the transmittance of CVDZnS is improved for the decrease of scatter losses at the grain boundary and structure defects.

Key words: CVDZnS, heat isostatic process(HIP), transmittance, X-ray diffraction
