Abstract

Abstract: Zeolites NaX, NaP and SOD were synthesized with hydrothermal treatment from the raw material of kaolin. The effects of temperature and the concentration of NaOH solution of the initial mixture on the crystallinity of zeolite were investigated via X-ray diffraction and water adsorption capacity. The binary crystallization phase diagram of three type zeolites and the rule of crystallization as well as phase transformation were obtained. Besides, the technical parameters of synthesizing zeolites were optimized to achieve the best synthetical conditions.

Key words: Kaolin, Zeolites, Binary crystallization phase diagram
