curium nitrate造句

• Reduction by Hydrogen Gas : A solution of curium trichloride is evaporated to dryness with pure nitric acid to produce curium nitrate.
• NH 3 OH is then added to the purified curium nitrate, and the resulting precipitate is collected and rinsed with deionized water.
• The curium nitrate is then ignited in air, producing curium oxide, believed to be an intermediate structure between CmO 2 and the formation of Cm 2 O 3.
• In other aerosolizations, instead of the addition of NH 3 OH to the purified curium nitrate, ammonium hydroxide is utilized to adjust the pH value of the solution to 9 . The increased basicity of the solution creates a curium hydroxide precipitate.
• While curium metal has been discovered to naturally exist as a mixture of 87.4 % 244 Cm, 8.4 % 243 Cm, 3.9 % other curium isotopes, and ~ 0.3 % of the daughter nuclide, plutonium, in most aerosolized syntheses of curium ( III ) oxide, curium metal is purified through solvent extraction of curium nitrate and " bis " ( 2-ethylhexyl ) phosphoric acid in toluene to remove the plutonium.
