Abstract
A technique for preparing high purity Li2CO3 powders has been developed through mechanochemical process coupled with the dissolution-filtration process. The first step as mechanochemical reaction of both Na2CO3 and LiCl mixtures was designed to obtain the primary Li2CO3 powders using a ball mill. The second step as the dissolution- filtration process was performed to obtain high purity Li2CO3 powders. Experimental results indicate that the three parameters of milling time, rotation speed, and ball-to-sample mass ratio can closely relate with purity of primary Li2CO3 powders. The XRD patterns of primary Li2CO3 powders indicate that mechanochemical reaction of both Na2CO3 and LiCl can be completed in 15 min under optimal conditions at rotation speed as 600 rpm, ball-to-sample mass ratio as 5/1, and molar ratio of Na2CO3 to LiCl as 1/2. The target products of Li2CO3 powders contain impurity of Na+ less than 0.1mass% with the minimum values as 0.073mass%. Two shapes of massive particles and smaller grains less than 1 μm in nano scale can be observed in the target products of Li2CO3 powders.
