Chemical compound
Lithium molybdate is aninorgnaic compound with thechemical formula Li2 MoO4 . It is a white solid formingtrigonal crystals.[ 3]
At standard conditions it isisostructural tophenacite (Be2 SiO4 ).[ 1] [ 4] Phrase transformations occur at elevated temperatures.[ 4]
Lithium molybdate can be prepared by reactinglithium carbonate andmolybdenum trioxide by asolid-state reaction route followed byrecrystallization .[ 1]
A related lithium molybdenum oxide (Li2 MoO2 ) with ahexagonal layered structure can be prepared by reacting Li2 MoO4 with Mo metal at 900 °C.[ 5] isomorphous withα-NaFeO2 (space group R3m, a = b = 2.8663 Å, c = 15.4743 Å, Z = 3).[ 5]
Lithium molybdate is used inpetroleum cracking catalysts.[ 3] n-hexane , the addition of molybdenum species to a Li/MgO catalyst results in the formation of lithium molybdate mixed oxide phases.[ 6] Li2 CO3 in the catalyst, maintaining high surface area and stability.[ 6]
Lithium molybdate is used ascorrosion inhibitor .[ 7]
Li2 MoO4 crystals have been found applicable forcryogenic phonon -scintillation detectors, which are used to investigate some rarenuclear processes .[ 8]
The use of Li2 MoO4 ceramics for antennas has been studied due to their low lossdielectric properties and the possibility to fabricate them by aroom-temperature densification method instead of conventionalsintering .[ 9] hollow glass microspheres (HGMS) to make low permittivity composite for lenses inlens antennas .[ 10]
