Abstract
Zinc Selenide ceramic was successfully fabricated by spark plasma sintering in the study. The ZnSe raw powders were handled with two different methods such as grinding and planetary ball milling, respectively. The relative density, microstructure and transmittance of the ZnSe ceramic sintered under the same sintering parameter with two type powders was investigated. The results shown that the performance of the powder processed by ball milling was more effective than that by grinding. Furthermore, the maximum relative density can reach 99.8% when the ZnSe powder treated by ball milling were sintered at 950 oC for 30 min with the heating rate of 10 oC/min under 100 MPa.
