Humic Acid Ceramic Deflocculant (Dolapix Analog)
CAS Number: 1415-93-6
Humic acid-based deflocculants are natural polyelectrolyte dispersants functionally analogous to commercial products such as Dolapix CE64. They adsorb strongly onto alumina and oxide surfaces, providing electrosteric stabilization and enabling ultra-low viscosity slips at high solids content. Suitable for colloidal processing, gel casting, and direct coagulation casting of advanced ceramics.
Technical Specifications

Applications
- Deflocculant for alumina colloidal processing
- Dispersant for gel casting of alumina and Si3N4
- Dispersant for direct coagulation casting of oxide ceramics
- Viscosity modifier in dense ceramic slurry systems
- Natural polyelectrolyte dispersant for oxide nanopowders
Key Features
- Natural, bio-sourced polyelectrolyte with strong adsorption on alumina
- Enables colloidal processing routes for high-density ceramic parts
- Cost-effective alternative to branded Dolapix-type dispersants
- Compatible with gel-casting monomer systems such as acrylamide
