Abstract

Abstract: Zinc pieces were adopted as raw material to provide nourishment for ZnO crystal growth, ZnO crystal has synthesized on the zinc foils through hydrothermal method. Distilled water, NH3?H2O, NaOH and butyl amine were used as mineralizer to keep hydrothermal environment as alkaline. The results show that ZnO crystal growth habit affect by concentration; molecular structure and solvent saturated vapor pressure of mineralizer remarkably, make the final crystal morphology difference. In the study, the author also speculated on the feature of crystal morphology by XRD data of diffraction intensity of crystal plane and validated by scanning electron microscope (SEM). Moreover, crystal growth mechanisms of ZnO crystallite on the zinc foil were discussed in detail.

Key words: Hydrothermal method, Zinc oxide crystallite, Crystal growth mechanism, Mineralizer, Diffraction intensity of crystal plane
