UsesUranyl nitrate can be used as an analytical reagent, as a lighting device in the photographic industry, and in the production of fine porcelain.
General DescriptionAcidic solution in water of uranyl nitrate, a radioactive yellow crystalline solid. Mildly chemically toxic. Contains nitric acid. Noncombustible, but will accelerate the burning of other combustible materials if concentrated or if the water evaporates. Large quantities may explode if exposed to fire. Produces toxic oxides of nitrogen if involved in fire. Radioactive materials emit certain rays which can be detected only by instruments. Unirradiated uranium is only mildly radioactive. Minimal radiation hazard during transportation. No protective shielding is required. Non-fissile (natural or depleted) uranium, containing not more than 1.0% u-235, cannot sustain a nuclear chain reaction.

Stability
Radioactive, but chemically stable. Strong oxidant. Hygroscopic. Incompatible with combustible materials, reducing agents. May react explosively with cellulose and certain organic solvents.
