Uranium is notable for the extremely high density of its metallic form: at 19.1 grams per cubic centimetre (0.69 lb/cu in), uranium is 68.4% more dense than lead. Depleted uranium, which has about the same density as natural uranium, is used when this high density is desirable but the higher radioactivity of natural uranium is not.

This process produces huge quantities of uranium that is depleted of uranium-235 and with a correspondingly increased fraction of uranium-238, called depleted uranium or 'DU'. To be considered 'depleted', the 235 U concentration should be no more than 0.3%. [ 124 ]
When fired, depleted uranium becomes ‘essentially an exotic metal dart fired at extraordinarily high speed’
Uranium(III) chloride is a green crystalline solid at room temperature. UCl 3 melts at 837 °C and boils at 1657 °C. Uranium(III) chloride has a density of 5500 kg/m 3 or 5.500 g/cm 3. Its composition by weight: Chlorine: 30.84% Uranium: 69.16%. Its formal oxidative states: Chlorine: −1 Uranium: +3
Uranium-238 is an alpha emitter, decaying through the 18-member uranium series into lead-206. The decay series of uranium-235 (historically called actino-uranium) has 15 members and ends in lead-207. The constant rates of decay in these series makes comparison of the ratios of parent-to-daughter elements useful in radiometric dating. Uranium ...
The key to effective shielding with depleted uranium ceramic concrete is maximum uranium oxide density. Unfortunately, the densest depleted uranium oxide is also the most chemically unstable. DUO 2 has a maximum theoretical density of 10.5 g/cm 3 at 95% purity. However, under oxidation conditions, this material readily transforms into the more ...
