A process for manufacturing uranium oxide powder from UF6 which comprises converting UF6 to UO2F2 by reaction of the UF6 with excess alcohol in gas phase and further converting the UO2F2 formed to uranium oxide under combustion of hydrocarbon formed in the gas phase reaction and the excessive alcohol with oxygen containing gas. The uranium oxide obtained in this way is low in fluorine content and high in activity. Therefore it is, a very suitable raw material for nuclear fuel.
