hi Arun,

i think you know the phase diagram. IWhen I see that LiAlO2 starts to form at 300 °C and the CO2 pressure starts to increase rapidly at 400 °C by decomposition of the Carbonate you might have to suppress the decomposition of the carbonates by higher CO2 pressure. The seconf route might be a gas reaction between gaseous LiO(g) , CO2(2) and solid gamma -Al2O3. This reaction occurs at lower temperature and the driving force, mixability (jomogeneous distribution of the components might be better than a solid-solid reaction.

Thanks Mr. Axel. i appreciate your help in answering my question.

we did delve into the gaseous Li2O based process, but the problem with it is highly costly. we are looking at something more cheaper to mfg.
