 T-ZnOw
 Nano T-ZnOw
Nano-tetrapod zinc oxide whiskers are prepared by vapor-phase oxidation of zinc pig under high temperature. The effects of content of molecular sieve, reaction temperature and system pressure on the morphology of T-ZnO, are examined. The products are identified to be pure ZnO with wurtzite structure by X-ray diffraction analysis （XRD）. But EDS analysis shows that the atom ratio of oxygen and zinc is below 1. The scanning electron microscopy （SEM） investigation indicates that content of molecular sieve, reaction temperature and system pressure have great effects on the morphology of T-ZnOw. Under constant pressure, the morphology of the whiskers changes with the increasing of reaction temperature. Nano T-ZnO, with complete and uniform structure can be obtained when the pressure and temperature are 11083Pa and 1038℃ respectively. While underconstant temperature, the dimension of the products reduces with the reducing of the pressure. Uniform nano T-ZnO. with root dimension of 20nm to 80nm and length of 300nm to 2μm could be obtained when the pressure is lower than 11083Pa.
