Effect of the SPS Parameters on the Density of Sintered ZnSe

In the present study، zinc selenide powder sintered by SPS method successfully completed. The effects of temperature and pressure parameters of SPS on the bulk density were investigated. To measure the density، Archimedes method، to investigate the microstructure، optical microscopy and SEM and to phase study، XRD were used. The results indicated that temperature and then pressure are the most effective and the maximum density (99. 3%) and minimum density (91. 1%) was obtained at 1100 ° C، 70 MPa and 1000 ° C، 30 MPa respectively (25 min soaking time). Also the phenomenon of plate’s crystallographic orientation was observed by XRD and was confirmed by SEM.
