摘要：
A process for obtaining Li2CO3 from Li2TiO3 Powder by wet chemistry was developed. This is considered useful in view of the recovery of the Li-6 isotope from lithium titanate breeder burned to its end of life in a fusion reactor. The process was optimized with respect to the chemical attack of titanate and the precipitation of carbonate from aqueous solutions to get a powder with chemical and morphological characteristics suitable for its reexploitation in the fabrication of Li2TiO3 pebbles. Reprocessing was also planned to adjust the Li-6 concentration to the desired value and to obtain a homogeneous distribution in the powder batch. Further development concerning reprocessing of sintered Li2TiO3 pebbles is in progress exploiting the results obtained with lithium titanate powders. (C) 2002 Elsevier Science B.V.
