| titleOfInvention | A kind of method that battery-level lithium carbonate is prepared using potassium carbonate as precipitating reagent |
| abstract | A kind of method that battery-level lithium carbonate is prepared using potassium carbonate as precipitating reagent, is related to chemical technology field, there is following steps completion, Alkali liquid compounding → removal of impurities → ion exchange → evaporation and concentration → reaction aging → filtration washing → drying → finished product；The beneficial effects of the present invention are：The present invention is reacted using potassium carbonate as precipitating reagent with lithium chloride prepares lithium carbonate, and the mother liquor finally obtained the Klorvess Liquid higher for purity, the mother liquor can be directly used for production potassium chloride or potassium carbonate, and no waste generates；Solves the problems, such as viscous wall more serious in reaction process with reaction temperature cooperation using crystal seed is added in；Using the problem of crystal seed, reaction temperature, mixing speed, combination of ultrasound avoid lithium carbonate crystal accumulation, size distribution is wide. |
