Zinc oxide whiskers by thermal oxidation method

ZnO whiskers were grown in quartz tube by thermal oxidation method. Zinc powder was heated in a horizontal quartz tube with a furnace at a temperature of 700°C for 2 hr, under normal atmosphere. Three different kinds of the products can be obtained after the oxidation process. One is transparent whi...
