The tungsten composite powder with rare-earth oxide, in which the component and amount of doped phase are different, has been studied by the liquid-solid blending method, pyrolysis and reduction etc The effects of original powder on reduction temperature and the doped phase on the degree of reduction are discussed It has been showed that the composite powder made by WO 2 9 has good overall characters The reducing degree of the powder is enhanced with the temperatnre increasing The powder with a large amount of the doped phase is more difficult to reduce than that of a small amount of the doped phase The powder of ternary system is also more difficult to reduce than that of binary system The tungsten composite powder with rare-earth oxide made by the liquid-solid blending method has fine size and uniform disperse phase
