摘要
本文报道了研究氧化钼结晶的一个新的实验方法及结果。把钼板在氧化性气氛中适当地加热到900℃后,获得了Mo_5O_(14)的单晶体。其中最大的单晶体尺寸为15×1.1mm,用Rutherford背散射技术(RBS)测定其厚度为310nm。在750℃加热后,观察到由许多氧化钼晶须所组成的分形结构。对氧化钼单晶的生长及分形结构的形成机理进行了讨论。
During a molybdenum metal sheet heated properly at 900℃ in an oxi-dizing ambient, the Mo_5O_(14) single crystals will grow. The size of the most coarsesingle crystals is up to 15×1.1 mm and 310 nm thick as measured by Rutherfordback scattering spectrometry. Some fractal structure consisting of many molybdenawhiskers are observed after heating at 750℃. An approach to explain the crystalgrowth and fractal structure has been discussed.
