Available Forms
- H-SSZ-13 powder (precursor for custom ion exchange)
- NH₄-SSZ-13 powder (alternative precursor, easier exchange)
- Cu-SSZ-13 powder (pre-exchanged, certified Cu loading)
- Fe-SSZ-13 powder (pre-exchanged, certified Fe loading)
- Washcoat-compatible powder (optimised particle size for coating)
Certificate of Analysis
Every shipment includes a batch-specific COA. For H/NH₄-forms: SiO₂/Al₂O₃, BET, Na₂O, particle size, XRD. For Cu/Fe-exchanged forms: all above plus metal loading by ICP-OES. Additional parameters on request: SEM, H₂-TPR, NH₃-TPD, hydrothermal aging test (800 °C/16h).
To request a sample with COA, specify your target SAR, metal form (H, NH₄, Cu, or Fe), metal loading if applicable, and application (mobile SCR, stationary SCR, or other).
