Description
Uranium(VI) Oxide, also known as Uranium Trioxide (UO3), is a versatile solid compound with significant applications in the nuclear fuel cycle. It exists in six well-defined stoichiometric modifications and a hypostoichiometric modification, UO2. Obtained through the thermal decomposition of uranyl compounds such as carbonates, oxalates, and nitrates, Uranium(VI) Oxide exhibits a small temperature-dependent paramagnetism and follows a general trend of inverse proportionality between the O/U ratio and the density of the material.
Uses
Used in Nuclear Fuel Industry:
Uranium(VI) Oxide is used as a nuclear fuel component for its ability to undergo fission, releasing a significant amount of energy that can be harnessed for electricity generation in nuclear power plants.
Used in Ceramic Industry:
Uranium(VI) Oxide is used as a pigment in the ceramic industry, taking advantage of its various color modifications, such as hexagonal brown, orange monoclinic, bright yellow rhomb, red cub, brick red tricl, and rhomb.
Used in Research and Development:
Uranium(VI) Oxide is utilized as a research material for studying its chemical properties, magnetic behavior, and thermal decomposition characteristics, contributing to the advancement of nuclear science and technology.
Purification Methods
The oxide is dissolved in HClO4 (to give a uranium content of 5%), and the solution is adjusted to pH 2 by addition of dilute ammonia. Dropwise addition of 30% H2O2, with rapid stirring, precipitated U(VI) peroxide, the pH being held constant during the precipitation, by addition of small amounts of the ammonia solution. Then H2O2 is added until further quantities caused no change in pH. After stirring for 1hour, the slurry is filtered through coarse filter paper in a Büchner funnel, washed with 1% H2O2 acidified to pH 2 with HClO4, then heated at 350o for three days in a large platinum dish [Baes J Phys Chem 60 878 1956].
Check Digit Verification of cas no
The CAS Registry Mumber 1344-58-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,3,4 and 4 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1344-58:
(6*1)+(5*3)+(4*4)+(3*4)+(2*5)+(1*8)=67
67 % 10 = 7
So 1344-58-7 is a valid CAS Registry Number.

Mg, Ca and Ba glutaratouranylates – Synthesis and structure
Novikov,Serezhkina,Grigoriev,Serezhkin
, p. 147 - 152 (2018)
Three novel uranyl coordination polymers were synthesized and structurally characterized by single crystal X-ray diffraction – [Mg(H2O)6][UO2(glt)(Hglt)]2·6H2O (1), [Ca(H2O)4][UO2(glt)(Hglt)]2·4H2O (2) and [Ba(H2O)5][UO2(glt)(Hglt)]2·2H2O (3), where glt = C5H6O42? (glutarate) and Hglt = C5H7O4? (hydroglutarate) anions. The structures of compounds 1–3 contain 1D [UO2(glt)(Hglt)]? units that belong to the AQ02B01 (A = UO22+, Q02 = glt, B01 = Hglt) crystallochemical group. The different roles of alkaline earth R2+ cations in the structures and the flexibility of the glutarate anions account for the structural distinctions of 1–3. The diverse ways for the connection between the R2+ ions and the [UO2(glt)(Hglt)]? chains, the water content and the geometry of the uranyl-glutarate units present the main structural features of the new complexes. A comparative analysis based on Pauling's second rule of 1–3 and alkali glutaratouranylates has allowed an explanation of their structural dissimilarity.
