O and ZnO whisker was synthesized via liquid precipitation reaction and sintering methods process. The phase，granularity

structure of crystal morphology of whiskers samples were characterized by X-ray diffraction (XRD)，scanning electron microscopy (SEM) and thermal analysis (TGDTA). The SEM result revealed that :①  the whiskers formed with fine dispersive capability

② the crystal formed with good whisker quality

③ the surface was smooth

and ④ the particle was dispersed in uniform distribution. From the point of growth units
