| Abstract: | It is well known that the change of metastable zeolite to a morr stable one depends upon the intrinsic properties of the zeolite and also the chemical environment in which it exists. We studied the probability of transformation of zeolite from one type to another when changing the chemical environment. We investigated respectively the transformation of added zeolite to F, AG4 or Ω type in its own formation environment and also studied the process and mechanism of the transformation of NaAto NaFzeolite in the chemical environment of NaF type formation. Scanning electron microscope, X-ray diffraction and high vacuum adsorption methods were employed in these studies. |
