采用一种新的方法，即在500-800°C常压下，用金属锌颗粒或其它形状的金属锌氧化，在短时间内制备出高收率、高纯度的四针状氧化锌晶须。对反应条件进行了分析，并与其它方法进行了比较。通过扫描电子显微镜（SEM）和X射线衍射（XRD）对产物进行了表征。结果表明，这是一种经济实用的制备氧化锌晶须的方法。提出了一个合适的炉腔容积与原料锌量之比。
Tetrapod-shaped ZnO whiskers were prepared with high yield and good purity in a short reaction time by a new method, the oxidation of pellets or otherwise shaped metallic zinc at 500–800°C under atmospheric pressure. The reaction conditions were analyzed and compared with other methods. The products were identified by scanning electron microscopy (SEM) and X-ray diffraction (XRD) analysis. The results show that this is a practical and economical method for manufacturing ZnO whiskers. A suitable ratio between the volume of the furnace chamber and the quantity of the material zinc is suggested.
