晶须是一种特殊形态,即十分纤细的单晶材料。一般晶须是一维形态,直径为零点几微米至几十微米,长度则有几十微米甚至几十毫米,少数晶须具有一定宽度,呈二维薄片状。晶须纯度极高,是完整的单晶结构,原子间键合力强,可达到或接近理论强度值。各种纯金属,氧化物,硅化物晶须的研究、生产和应用愈来愈受重视,成为复合材料发展的一个重要方面,如钛晶须,二氧化 Whiskers are a special form of very fine single crystal material. Whiskers are generally one-dimensional morphology, the diameter of a few tenths of microns to tens of microns, the length of tens of microns or even tens of millimeters, a few whiskers have a certain width, was two-dimensional flake. Whisker purity is extremely high, is a complete single crystal structure, strong bonding between atoms, can reach or close to the theoretical value. A variety of pure metals, oxides, silicide whiskers research, production and application of more and more attention has become an important aspect of the development of composites, such as titanium whiskers, dioxide
