Abstract
A process for preparing a crude zinc selenide (ZnSe) powder includes mixing powder of element Se with powder of element Zn in a proportion of (1-1.35):1, putting the mixture in an indirect heat crucible to be placed in a vacuum room, heating the crucible up to 300-380 deg.C. Furthermore, the high purity of zinc selenide powder can be obtained through grinding and annealing the crude reactant under the conditions of vacuum with a temp. of 550-700 deg.C and 90 minutes. Zinc selenide (ZnSe) powder is an important photoelectric material used in defense industry.
Description
