Lithium Tungstate

Lithium tungstate is a kind of BeSiO3 stone lattice which is colorless triangular crystal. its physical properties are shown below：the chemical formula: Li2O4W, molecular weight: 261.7196, density: 3.71g/ml, Solubility: soluble in water, but insoluble in ethanol. Its chemical properties are as follows: It can decompose in acid; On the other hand, heating it at temperature of 500 ~ 800 ℃, and then passed through H2 can restore to the tungsten bronze, and then heated to 600 ℃ generated WO2, the final product is W (β type) . Lithium tungstate is stable at room temperature and atmospheric pressure, but to avoid the light, open flame and heat, so it should be sealed and stored in where is cool and dry place. In addition, Li2O4W has acutely toxic, if human skin and eye contact it will cause inflammation and other symptoms, so when during at the operation should to take some protective gear. And Li2O4W has a certain degree pollution of water, the factories can not let undiluted or large number products to reach ground water, water course or sewage system, besides, without government permission do not allow material into the surrounding environment.
Lithium tungstate synthesis method: dissolution WO3 in Li (OH) or Li2CO3 solution to obtain Li2WO4.
