Using WO3 and WO2 as the starting material, the change of the particle size on the H2-reduction process was taken by a measurement of specific surface area, and the effect of particle size of the starting material on the particle size of the produced W was investigated. From the result, it was found that, in the case of the smaller particle size of W than that of WO3 is obtained, the particle size is not depend on that of WO3, especially, on the reduction process of WO2 to W, the particle size of W obtained is not affected by that of WO2, but a similar particle size of W is obtained.
