in sodium aluminate solution on precipitation rate, lithium content, morphology, and crystallization of alumina trihydrate (ATH) was investigated. Results showed that increasing lithium ion concentration...-shaped ATH attached on the coarse particles also benefited the secondary nucleation and led to the poor strength of alumina. All results will further contribute to improving the quality of alumina. Key......
