摘要
Hydrothermal synthesis of the natural, alkaline-earth zeolites via the alteration of Y-zeolite is presented. Synthetic versions of the zeolites harmotome, heulandite, brewsterite and gmelinite are synthesized from Y-zeolite using alkaline-earth cation containing solutions. The effect of the composition of the starting zeolite, the composition of the solution phase, the presence or absence of seeds and the experimental conditions are discussed.
