Lithium tungstate is a kind of colorless triangular crystal with BeSiO3 crystal lattice. It is easily soluble in water and insoluble in ethanol. It is easy to decompose in acid.
Its CAS No. is 13568-45-1. Molecular formula is Li2OW4. Molecular weight is 261.72000. Density is 3.71g/mL (25/4 °C). Li2OW4 can be prepared by dissolving WO3 in Li (OH) or Li2CO3 solution.
Li2OW4 is stable under room temperature and pressure. But, it should also avoid light, fire and high temperature. It should be sealed and stored in cool, ventilated and dry place. Be careful not to breathe dust. Skin and eye should not be exposed to dust. It is harmful to water so that you can not pour into environment without government's permission. It can be reducted into tungsten bronze by H2 under 500~800 degree celsius. WO2 is obtained after heating to 600 degree celsius. The final product is W.
