Uranate

<p>A uranate is a <a href="/facts/Ternary_compound/F8GKdouD">ternary</a> <a href="/facts/Oxide/DXtoVe1C">oxide</a> involving the element <a href="/facts/Uranium/n2sGWBzU">uranium</a> in one of the <a href="/facts/Oxidation_state/W53W6s6V">oxidation states</a> 4, 5 or 6. A typical <a href="/facts/Chemical_formula/hghUtthl">chemical formula</a> is MxUyOz, where M represents a cation. The uranium atom in uranates(VI) has two short collinear U–O bonds and either four or six more next nearest oxygen atoms. The structures are infinite lattice structures with the uranium atoms linked by bridging oxygen atoms. 
</p><p>Uranium oxides are the foundation of the nuclear fuel cycle ("<a href="/facts/Ammonium_diuranate/F8z5ytq6">ammonium diuranate</a>" and "<a href="/facts/Sodium_diuranate/rWssUrVq">sodium diuranate</a>" are intermediates in the production of uranium oxide <a href="/facts/Nuclear_fuel/8RhAomlJ">nuclear fuels</a>) and their long-term geological disposal requires a thorough understanding of their chemical reactivity, phase transitions, and physical and chemical properties.
