When a molybdenum sheet was heated properly at 900℃ in an oxidizing atmosphere, Mo_5O_(14) single crystals will grow.The size of the most coarse single crystal is up to 15×1.1 mm and 310 nm thick as measured by Rutherford backscattering spectrometry.Some fractal structure consisting of many molybdena whiskers were observed after heating at 750℃.An approach to explain the crystal growth and fractal structure has been discussed.
