Al and Si bonding at the molecular level under various conditions allows for a tunable conformation of the zeolite components leading to:
- Faster crystallization
- Controlled morphology
- High crystallinity
- Improved yield
- Reduced SDA usage
- Tunable SAR
- Microporosity consistent with theoretical standards
Nalco Water has developed an aluminum precursor for zeolite synthesis that is free of halide and sulfate. The product enables a corrosion free crystallization environment with high basicity, eliminating the need for excess sodium and Structure Directing Agent (SDA), and leading to higher phase purity. The aluminum precursor is available in liquid or solid forms containing 14% and 44% Al2O3 respectively.
