The ion exchange reaction and behavior for the Li1.3Ti1.7Al0.3(PO4)3 and Na1.3Ti1.7Al0.3(PO4)3 in NaNO3 and AgNO3 solutions were investigated at different temperatures. The experimental results show that the Li1.3Ti1.7Al0.3(PO4)3 and Na1.3Ti1.7Al0.3(PO4)3 have very high ion exchange selectivity to Naand Agin NaNO3 and AgNO3 solutions, and the selectivity to Ag is higher than that to Na. The Ag/Li and Ag/Na ion exchange reaction rate increased obviously with increasing temperature.

Key words: Li1.3Ti1.7Al0.3(PO4)3, Na1.3Ti1.7Al0.3(PO4)3, ion exchange
