Abstract: Alumination of ZK-4, sodalite and NaAzeolites was carried out by gas-solid replacement reaction at a high temperature. Chemical analysis, effluent gas analysis, XRD, IR, SEMand 29Si magic angle spinning NMRshowed that the Al-O-Al linkage is likely present in the framework of aluminated-ZK-4, aluminated-sodalite and aluminated-NaAzeolites after the three kinds of zeolites were aluminated at a elevated temperature.

Key words: Alumination, Lowenstein's law, Gas-solid replacement reaction
