Abstract
Calcination of kaolinite at 750 degrees C results in metakaolinite (MK ). Hydrothermal digestion of a slurry of MK and zinc oxide at similar to 120 degrees C results in the formation of zinc exchanged zeolite A in a single step. Addition of silica to the above system and digestion results in zinc exchanged zeolite P. Thus, syntheses of two types of zinc exchanged zeolites are obtained from clay.
