Fabrication of High Dense ZnSe Ceramic by Spark Plasma Sintering: The Effect of the Powder Process Method

摘要

Zinc Selenide ceramic was successfully fabricated byspark 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 ZnSe ceramic with the maximum relative density of 99.8% and the maximum infrared transmission of 62% when the ZnSe powder treated by ball milling and sintered at 950 °C for 30min with the heating rate of 10 °C/min under lOOMPa.
