| Pore size | 5.1-5.6 Å | 10-MR MFI channels |
| Pore volume (micropore) | 0.15-0.20 cm³/g | t-plot method |
| Na₂O content | ≤0.05 wt% (H-form) | XRF or AAS |
| Particle size (D50) | 0.1-5 μm | Laser diffraction |
| Loss on Ignition | ≤5 wt% | 800 °C, 2h |
| XRD crystallinity | ≥90% | vs MFI reference standard |
| Framework | MFI | XRD confirmation |
Available Forms
- H-ZSM-5 powder (acidic, ready to use)
- NH₄-ZSM-5 powder (calcines to H-form at 500-550 °C)
- Na-ZSM-5 powder (ion-exchange precursor)
- ZSM-5 extrudates (1.5-3 mm, custom binders)
- Phosphorus-stabilised ZSM-5 (for severe hydrothermal FCC service)
Certificate of Analysis
Every shipment includes a batch-specific COA with: SiO₂/Al₂O₃ ratio, BET surface area, Na₂O content, particle size distribution, LOI, and XRD crystallinity. Additional parameters available on request: SEM imaging, NH₃-TPD acidity, ²⁷Al MAS NMR.
To request a sample with COA, specify your target Si/Al ratio, ionic form, particle size, and application.
