- Jun 25, 2018 -

Include the following contents: Mix high-purity lithium carbonate with pure water, introduce carbon dioxide gas, perform carbonization reaction to obtain lithium bicarbonate solution, precision filter lithium bicarbonate solution, pass through filtered lithium bicarbonate solution Hydrogen fluoride gas is stirred and neutralized, the pH is controlled to 0.5-3 to obtain a lithium fluoride slurry; the lithium fluoride slurry is separated by centrifugation; the separated solid lithium fluoride is dried out Finished product. The method of the invention has the advantages of simple process, high purity of lithium fluoride, good fluidity, no alkaline impurities, neutrality, and product-grade lithium fluoride grade.
