Influence of heat treatment conditions on the microstructure6p.- Nano-W powder was prepared from voilet tungsten oxides by hydrogen reduction, and through heat treatment on the samples. Then , we have characterized the sample morphology, phase, content, specific surface area and pore structure, analyzed the latice change and the growth mechanism of the grain.
