Ammonium Carboxymethyl Cellulose (CMC-NH4) is a high-performance cellulose derivative specially developed for SCR denitrification catalyst manufacturing, honeycomb ceramics, and advanced ceramic processing applications.
CMC-NH4 is the ammonium salt form of carboxymethyl cellulose, produced through chemical modification of natural cellulose. It is a white, odorless, water-soluble powder with excellent binding ability, rheological control, dispersion performance, and extrusion processing properties.
Compared with conventional Sodium Carboxymethyl Cellulose (CMC-Na), CMC-NH4 offers advantages including sodium-free composition, ultra-low ash content, and cleaner thermal decomposition behavior, making it highly suitable for high-temperature ceramic processing and catalyst production.
CMC-NH4 is widely used as a functional binder and processing additive in:
- SCR denitrification catalysts
- Honeycomb ceramic substrates
- Automotive emission catalysts
- Lithium battery electrode materials
- Electronic ceramic components

CMC-NH4 generates extremely low inorganic residue during high-temperature decomposition.
- Minimizes contamination during catalyst manufacturing
- Improves purity of ceramic products
- Suitable for high-temperature calcination processes
- Supports cleaner ceramic structures
Unlike CMC-Na, CMC-NH4 does not introduce sodium ions into the formulation system.
- Prevents sodium contamination in catalyst materials
- Improves compatibility with SCR catalyst formulations
- Suitable for high-purity ceramic applications
- Reduces potential impact of alkali metal impurities
CMC-NH4 provides strong binding and rheological control during ceramic forming and catalyst extrusion processes.
It helps improve:
- Green body strength
- Particle bonding
- Extrusion smoothness
- Slurry stability
- Dimensional consistency
As a result, CMC-NH4 helps manufacturers achieve stable production of honeycomb structures and catalyst blocks with improved mechanical properties.
During drying, calcination, and sintering processes, CMC-NH4 decomposes efficiently with minimal residue.
- Cleaner burnout process
- Reduced impurities after firing
- Improved ceramic structure stability
- Better product quality consistency
