Research on the Microstructure of Tungsten Oxides

The microstructure of tungsten oxides was investigated by using scanning electron microscopy, transmission electron microscopy and so on.The results show that different tungsten oxides, including violet tungsten oxide, blue tungsten oxide and yellow tungsten oxide, are of different microstructure.Especially, violet tungsten oxide is of particular monocrystal bar structure and suitable for producing fine tungsten powders.
