Chemical compound
Lithium aluminate (LiAlO 2), also called lithium aluminium oxide, is an inorganic chemical compound, an aluminate of lithium. In microelectronics, lithium aluminate is considered as a lattice matching substrate for gallium nitride.[citation needed] In nuclear technology, lithium aluminate is of interest as a solid tritium breeder material, for preparing tritium fuel for nuclear fusion.[citation needed][3]
Lithium aluminate is a layered double hydroxide (LDH) with a crystal structure resembling that of hydrotalcite.[dubious – discuss][clarification needed] Lithium aluminate solubility at high pH (12.5 – 13.5) is much lower than that of aluminium oxides. In the conditioning of low- and intermediate level radioactive waste (LILW), lithium nitrate is sometimes used as additive to cement to minimise aluminium corrosion at high pH and subsequent hydrogen production.[4] Indeed, upon addition of lithium nitrate to cement, a passive layer of LiH(AlO 2) 2 · 5 H 2O is formed onto the surface of metallic aluminium waste immobilised in mortar. The lithium aluminate layer is insoluble in cement pore water and protects the underlying aluminium oxide covering the metallic aluminium from dissolution at high pH. It is also a pore filler.[5] This hinders the aluminium oxidation by the protons of water and reduces the hydrogen evolution rate by a factor of 10.[6]
Lithium aluminate also finds its use as an inert electrolyte support material in molten carbonate fuel cells, where the electrolyte may be a mixture of lithium carbonate, potassium carbonate, and sodium carbonate.[7]
