Transparent ZnS Ceramics by Sintering of High Purity Monodisperse Nanopowders

Résumé

We report an efficient way of preparing transparent ZnS ceramics using the hot-pressing technique. It has been found that the transparency is highly dependent on the purity and the grain size distribution of the starting ZnS powders. Highly pure and monodisperse ZnS powders have been obtained by posttreatment of the precipitated powders in a H2S/N2 flow for 2 h at 600°C. The obtained ZnS ceramics show fully dense and homogeneous microstructure with average grain size of ~1 μm and smooth grain boundaries, leading to an excellent transmission of around 70% in the mid- and far- IR regions. The preparation technique described in this study is highly reproducible.
