The processes of directly recycling high density tungsten alloy by oxidation reduction technique were investigated. The particle size of recycled powder is fine, and the shape of powder particle is regular when the final reduction temperature is 850?℃, in which the average size of the tungsten alloy particles reduced is about 1.5?μm. The average size of the alloy particles increase to 6?μm and 9?μm when increasing the reduction temperature to 900?℃ and 950?℃, respectively. However, if the reduction temperature is higher than 900?℃, the surface feature of powder is complicated. Increasing reduction temperature from 900?℃ to 950?℃, the content of oxygen of recycled powder decreases from 0.231?4% to 0.170?0%, and powder particles grow slightly. It has been also found that the chemical composition of the recycled alloy powder is the same as the initial powder.
