Abstract
The present application provides a lithium fluoride, a preparation method therefor and use thereof, where a mass content of carbonate in the lithium fluoride is less than or equal to 1000 mg/kg; a D10 of the lithium fluoride is less than or equal to 10 μm, a D50 is less than or equal to 20 μm, and a bulk density ranges from 0.9 g/cm3 to 1.2 g/cm3.
Claims15
A lithium fluoride, wherein a mass content of carbonate in the lithium fluoride is less than or equal to 1000 mg/kg;
- a D10 of the lithium fluoride is less than or equal to 10 μm, a D50 is greater than or equal to 1 μm and less than 15 μm, and a bulk density ranges from 0.9 g/cm3 to 1.2 g/cm3;
- and
- a purity of the lithium fluoride is greater than 99.8%.
A preparation method for a lithium fluoride, comprising the following steps:
- 1) mixing lithium carbonate with water and performing a slurrying treatment to form a lithium carbonate slurry having a mass percentage content of lithium carbonate ranging from 10% to 30%;
- and
- 2) adding hydrofluoric acid to the lithium carbonate slurry, enabling the system to react at a pH ranging from 3 to 6 until the pH of a reaction system shows no change, to obtain a reaction product, and subjecting the reaction product to a microwave drying treatment to obtain the lithium fluoride;
- wherein a reaction temperature ranges from 10° C. to 70° C.;
- and
- a microwave frequency of the microwave drying treatment ranges from 900 MHz to 1100 MHz, and a microwave treatment time ranges from 1 h to 2 h.
