Abstract 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.

Key words: molybdena single crystal fractal structure
