After calcination of ammonium tungstate into tungsten trioxide, the tungsten trioxide is reduced, and then the tungsten trioxide reduced tungsten powder is oxidized and reduced twice in a cycle, and the particle size distribution is between 0.1 and 0.5 μm. %, submicron tungsten powder with a specific surface area of 2.684m2/g.
2) This cyclic redox method has the advantages of simple and easy process route, easy control of process parameters, simple equipment and suitable for industrial mass production, etc.
