Abstract: The hot isostatic pressing of zinc sulfide, obtained by chemical vapor deposition technology, are studied to improve its quality characteristics. As a result of the studies carried out in the visible and near IR regions of the spectrum, the transmission of the treated samples was increased by 6–7 times compared to the untreated ones. In the wavelength range of 3–10 $\mu$m, the light transmission of the treated samples reached the theoretical limit.

Keywords: chalcogenides, zinc sulfide, chemical vapor deposition, hot isostatic pressing.
