Effect of Chemical Vapor Deposition Process on Mechanical Properties of ZnS

The influencing factors and control methods of CVD technic on mechanical properties of materials during the preparation of ZnS deposited by chemical vapor deposition (CVD) was introduced in this article. The internal structure and defects of the ZnS samples prepared by different technics were studied by XRD(X-Ray Diffraction), SEM (scanning electron microscope) and metalloscope,the control technology of grain size in CVD growth is proposed. The results indicate that designing reasonable jet structure and creating stable growing condition are conducive to improve the uniformity of CVD ZnS blanks and inhibit the formation of material defects. The mechanical properties of ZnS materials is improved consequently.
