“…The initial texture of the microcrystalline CVD-grown source material used for SSR experiments has been studied by Xray diffraction and electron microscopy [13]. X -ray pole figures indicate clearly (111) as preferential orientation, in agreement with the work of Hartmann et al [15] on polycrystalline ZnSe layers grown by lowpressure CVD in which (111) as well as (422) and (331) have been identified as preferential growth directions.…”

“…The use of the texture or orientation index as a measure of texture in polycrystalline XRD samples has been described for CVD ZnS 24 and CVD ZnSe 43 . Determination of the index consists of taking the ratio between the fraction of the intensity of an observed peak to the sum of all the observed peaks and the fraction of the intensity of the peak in an ideally isotropic sample to the sum of all ideal peak intensities …”

Structural changes from processing in polytype‐rich zinc sulfide (ZnS) are complex and poorly understood. In this study, recrystallization was induced in chemical vapor deposited ZnS by annealing and hot isostatic pressing (HIPping). Samples were characterized using optical microscopy, SEM, TEM, electron diffraction, polycrystalline and powder X‐ray diffraction, and transmission spectroscopy. Recrystallization was found to reduce the hexagonality and increase the {111} texture of as‐deposited ZnS. Changes in hexagonality and texture can occur independently of each other. HIPped ZnS with superior transmission exhibits both a change in texture and a reduction in hexagonal content. Reduction in hexagonality, alone, was not sufficient to improve optical transmission from the visible to the infrared. For the first time, the effects of pressure, temperature, and the presence of platinum on recrystallization during commercial ZnS HIPping are separated and identified. Platinum was found to actively promote recrystallization and silver demonstrated a similar effect. Several theories focusing on the unique polytypic nature of ZnS are offered to explain the changes in structure and properties occurring during recrystallization. These findings contribute to a broader understanding of the nature of order–disorder and martensitic phase transformations in ceramic materials.

“…79,81,82 Clearly there are differences in materials grown from H 2 S and those grown from S, and a similar phenomenon has been shown for zinc selenide. 83 The mechanisms behind the microstructural and optical changes after post-processing (i.e. annealing or hot-isostatic pressing) are still not clear.…”

The materials community realized that zinc sulfide (ZnS) was an important optical material for infrared windows over forty years ago. Chemical vapor deposition (CVD) quickly became the method of choice for producing large ZnS windows and domes. In addition to the development initiated in the United States, several international efforts for understanding the processing and properties of CVD ZnS are notable. This paper summarizes the published history of non-U.S. CVD ZnS development including the significant efforts in the United Kingdom, the former Soviet Union, Israel, China, and Japan.
