 Abstract: This chapter discusses the influence of different silica sources on the crystallization kinetics of zeolite beta. Zeolite beta is synthesized with different silicon sources. The dissolution of the silicon sources and the reaction temperature determines the crystallization rate of the zeolite. Silica sol reacted rapidly at 110, 140, and 170°C while fumed silica and tetraethyl orthosilicate (TEOS) only reacted readily at 170°C. The aluminum content in the reaction gel determines the termination of the crystal growth: after all aluminum is consumed, the crystal growth stopped. The acidic properties of the obtained materials are very similar, but a significant influence of the silicon source on the particle size of the resulting zeolite is observed.
