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

Uses

[edit]

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]
