Finely divided uranium metal presents a fire hazard because uranium is pyrophoric; small grains will ignite spontaneously in air at room temperature. [12] Uranium metal is commonly handled with gloves as a sufficient precaution. [143] Uranium concentrate is handled and contained so as to ensure that people do not inhale or ingest it. [143]
Uranium is a highly soluble and radioactive heavy metal. It can be easily dissolved, transported and precipitated within groundwater by subtle changes in oxidation conditions. Uranium does not usually form very insoluble mineral species, which is a further factor in the wide variety of geological conditions and places in which uranium ...
This is when uranium glass reached the height of its popularity in the United States between 1958 and 1978, with more than 4 million pieces of decorative uranium produced, according to Oak Ridge ...
Uranium metal heated to 250 to 300 °C (482 to 572 °F) reacts with hydrogen to form uranium hydride. Even higher temperatures will reversibly remove the hydrogen. This property makes uranium hydrides convenient starting materials to create reactive uranium powder along with various uranium carbide, nitride, and halide compounds. [6]

Enrichment processes generate uranium with a higher-than-natural concentration of lower-mass-number uranium isotopes (in particular 235 U, which is the uranium isotope supporting the fission chain reaction) with the bulk of the feed ending up as depleted uranium. Natural uranium metal contains about 0.71% 235 U, 99.28% 238 U, and about 0.0054% ...

Uranium metal can also be made through electrolysis of KUF 5 or UF 4, dissolved in a molten CaCl 2 and NaCl. Very pure uranium can be produced through the thermal decomposition of uranium halides on a hot filament. The uranium isotope 235 U is used as the fuel for nuclear reactors and nuclear weapons. It is the only isotope existing in nature ...
