Abstract

ZnO whiskers were rapidly microwave synthesized from micron ZnO powder with Ti reducing agent. The compositions and microstructures of the products were studied using X-ray diffraction, scanning electron microscopy, and energy dispersive X-ray spectroscopy. Results showed that white flocculent ZnO powder began forming at 600 °C and increased in amount with increasing temperature. In the sample obtained at 800 °C, the tetrapod ZnO whiskers had rod-like feet with lengths of 1.5–3 μm and diameters of approximately 0.2–0.5 μm. The reduction reaction was completed at 1 100°C. Coarser and irregularly shaped ZnO whiskers with thick roots and sharp tips formed at 1 100°C.
