Supercritical Debinding of Injection Molded Ceramics
Extraction of organic additives from extrusion‐molded cylinders of alumina by a supercritical fluid is investigated. Hildebrand parameters alone are not adequate to predict conditions for optimal polymer extraction with supercritical CO2. The results obtained with two models developed for the kineti...

| description | Extraction of organic additives from extrusion‐molded cylinders of alumina by a supercritical fluid is investigated. Hildebrand parameters alone are not adequate to predict conditions for optimal polymer extraction with supercritical CO2. The results obtained with two models developed for the kinetics of binder extraction suggest that polymer extraction from green samples is controlled by diffusion without development of a reaction front. The solubility and diffusivity of polymers both affect the extraction rate, with opposite pressure and temperature dependencies. |
