Chemical compound

Lithium molybdate (Li₂MoO₄) is a chemical compound. It is mainly used as an inhibitor in some types of industrial air conditioning.

Uses

Lithium molybdate is used as corrosion inhibitor in LiBr (Lithium bromide) absorption chiller for industrial central air conditioning. It is manufactured and shipped as either a colorless, transparent fluid or a white crystal powder. In either state it not classified as a hazardous material.

Li₂MoO₄ crystals have been found applicable for cryogenic phonon-scintillation detectors, which are used to investigate some rare nuclear processes.^[2] The use of Li₂MoO₄ ceramics for antennas has been studied due to their low loss dielectric properties and the possibility to fabricate them by a room-temperature densification method instead of conventional sintering.^[3] Li₂MoO₄ (LMO) have also been used with hollow glass microspheres (HGMS) to make low permittivity composite which has been used to make lenses for lens antennas.^[4]
