چکیده انگلیسی
• Zeolite omega was synthesized from magadiite in a glycerol–water system.
• Changes of medium-range structure during the crystallization were investigated.
• Formation pathway for zeolite omega is proposed.
Changes of medium-range structure during the crystallization of zeolite omega from magadiite were characterized. It is found that although the long-range order of magadiite is collapsed in the initial stage, parts of 5-member rings and 6-member rings are still preserved as secondary building units. The fraction of 5-member rings and 6-member rings increases as the crystallization progresses. The 4-member ring chains are formed at a stage later than that of 5-member rings and 6-member rings.
