"uranium oxide": any of a series of oxides of uranium that are usually regarded as definite compounds but are better considered phases with a range of compositions: as ... c: the trioxide UO3 that is obtained as a light yellow to orange to brick-red amorphous or crystalline substance usually by heating uranyl nitrate or ammonium di-uranate, that loses oxygen on heating to form tri-uranium oct-oxide, and that is sometimes used as a pigment for green-yellow colors in glass. 2, record 1, English, - uranium%20trioxide

La purification [des concentrés d'uranium] consiste à traiter l'uranate par l'acide nitrique pour le transformer en nitrate d'uranyle, qui est purifié par extraction à l'aide de solvants organiques. Dans l'élaboration, on décompose par la chaleur le nitrate d'uranyle pur en trioxyde d'uranium UO3, qui, par réduction à l'hydrogène, conduit au dioxyde UO2. 1, record 1, French, - trioxyde%20d%27uranium
