MANUFACTURING METHOD OF HIGHLY PURE ALPHA-LIALO2

摘要

The present invention relates to a method for preparing high-purity alpha-lithium aluminate (a-LiAlO 2 ). More specifically, the invention relates to a method for preparing alpha-lithium aluminate, which comprises mixing Al(OH) 3 and Li2 CO3 at a molar ratio of from 1: 1 to 3: 1 and heat-treating the mixture at a temperature of 500-800 0C and which can prepare high-purity alpha-lithium aluminate without needing to carry out a washing process.
