تأثير بعض العوامل على تشكل الزيوليت الألمينوسيليكاتي

We used the hydrothermal method to synthesize the aluminosilicate zeolite , we studied the influence of alumina source and the role of the structural directing agent on the formation of zeolite .We had used nitrogen absorption method at 77O K to determine some textural factors , defferential themal analysis ( TG-DTA) to determine thermal effects and X.R.D to certify the crystanility . The source of alumina didn't show clearly any difference in the structure, while the CTMABr makes the structure less stable and leads to better crystanility than Et3N .The thermal treatment showed clear effect on the textural in the case of CTMABr while this treatment showed low influence in the case of using Et3N.
