【Abstract】 The proportion of raw materials has a great effect on the type and purity of molecular sieves when they are synthesized by water thermal synthesis. By changing the proportion of raw materials, different kinds of molecular sieves are obtained, such as those of 4A zeolite, B zeolite, X zeolite ,hydroxy sodalite and their mixtures.更多还原
