摘要：

This is a comparative study of the synthesis of zeolite A from metakaolinite using both conventional and microwave-assisted heating. The effects of reaction conditions on the rate of formation, crystallinity and actual % yield of zeolite A were investigated. Reaction parameters such as different NaOH molarities (1.0-5.0 M), temperatures (70 and 80 degrees C), durations (1-8 h) as well as the effect of seeding percentage (1-4%) were tested. The rate of zeolite A formation was found to increase by 2-3 times in microwave treated samples with a notable enhancement in the product crystallinity and % yield whether seeded or un-seeded.
