Feature
Lithium tungstate is an inorganic compound with the chemical formula Li2Wo4. It is a white solid soluble in water. This compound is one of several orthotungstates with a tetrahedral WO42− anion.
Chemical formula: Li2WO4
Appearance white: solid
Density: 4.56 g/cm3
Application
Lithium tungstate is used to produce high-density polytungstate (metatungstate) aqueous solution. Like other high-density fluids, such solutions are often used to separate minerals and other solids. These can reach a density of 2.95 at 25°C and 3.6 in hot water.
The use of this lithium and sodium tungstate anion was developed in the 1980s and early 1990s to address toxicity and safety concerns with existing organic high-density fluids. Unlike methylene iodide and bromoform, polytungstates and heteropolytungstates can be used more safely in indoor environments without fume hoods, with common sense safety precautions such as protective gloves and safety glasses.
