Dear Cindy,

Sodium aluminate is cheap, and easy to buy from a commercial firm.

Using sulfate instead of aluminate culd, 1) alter the pH or the reacting mixture, 2) risk presence of sulfate in the obtained zeolie. And, of course, you would still have to add a source of sodium if you use aluminium sulfate.

Best wishes,

Carlos

Ok..That is possible, but different conditions (pH, hydrothermal temperature and pressure, reaction time, and sodium source) should be used. Please check previous experiments already reported in the literature.

Best regards.
