Paper Title:
Synthesis of Tetrapod ZnO by Direct Oxidation of Zinc Metal at Elevated Temperature
  Abstract

ZnO product with tetrapod-shaped morphology was simply synthesized by controlling the evaporation and oxidation process of zinc metal. Pure bulk industrial zinc (99.995%) was first cast into small zinc pieces with a weight about 10~50g and then was heated in an alumina crucible in a furnace from room temperature to 1000~1250°C holding temperature, where the zinc pieces were vaporized and oxidized into zinc oxide products. The effects of zinc amount and holding temperature on the morphology of zinc oxide were investigated in this study. The products were confirmed to be zinc oxide with hexagonal wurtzite structure by X-ray diffraction analysis (XRD). Scanning electronic microscopy (SEM) analysis indicated that the morphologies of the products were T-ZnO whisker when the adding amounts of the zinc pieces were 20g and 30g, respectively. Based on the experimental results, it was speculated that crystal growth of T-ZnO comprised the formation of nuclei and the growth of need-like whisker.
