Uranium glass is used as one of several intermediate glasses in what is known to scientific glass blowers as a 'graded seal'. This is typically used in glass-to-metal seals such as tungsten and molybdenum or nickel based alloys such as Kovar, as an intermediary glass between the metal sealing glass and lower expansion borosilicate glass.
UO 3-based ceramics become green or black when fired in a reducing atmosphere and yellow to orange when fired with oxygen. Orange-coloured Fiestaware is a well-known example of a product with a uranium-based glaze. UO 3-has also been used in formulations of enamel, uranium glass, and porcelain.
Ball-and-stick model of UO 2+ 2 The uranyl ion, showing the U–O bond order of 3. The uranyl ion is an oxycation of uranium in the oxidation state +6, with the chemical formula UO 2+ 2. It has a linear structure with short U–O bonds, indicative of the presence of multiple bonds between uranium and oxygen.
The most important oxidation states of uranium are uranium(IV) and uranium(VI), and their two corresponding oxides are, respectively, uranium dioxide (UO 2) and uranium trioxide (UO 3). [2] Other uranium oxides such as uranium monoxide (UO), diuranium pentoxide (U 2 O 5), and uranium peroxide (UO 4 ·2H 2 O) also exist.
The amount of uranium in air is usually very small; however, people who work in factories that process phosphate fertilizers, live near government facilities that made or tested nuclear weapons, live or work near a modern battlefield where depleted uranium weapons have been used, or live or work near a coal-fired power plant, facilities that ...
Structurally, it is a coordination polymer with formula UO 2 (CH 3 CO 2) 2 (H 2 O)·H 2 O. Structure. In the polymer, uranyl (UO 2 2+) centers are bridged by acetate ...
Uranyl peroxide or uranium peroxide hydrate (UO 4 ·nH 2 O) is a pale-yellow, soluble peroxide of uranium.It is found to be present at one stage of the enriched uranium fuel cycle and in yellowcake prepared via the in situ leaching and resin ion exchange system.
Uranium trioxide or uranium(VI) oxide (UO 3) Triuranium octoxide (U 3 O 8), the most stable uranium oxide; yellowcake typically contains 70 to 90 percent triuranium octoxide) Uranyl peroxide (UO 2 O 2 or UO 4) Amorphous uranium(VI) oxide (Am-U 2 O 7) Uranium dioxide is oxidized in contact with oxygen to form triuranium octoxide. 3 UO 2 + O 2 ...
