The effects of TEMPO-oxidized cellulose nanofiber (TCNF) as an additive on ceramic slip casting process were investigated. Rheological properties of ceramic slurry, formability and sintered body properties were evaluated. By means of the precipitation test and viscosity measurement, development of thixotropic property and improvement of dispersion stability of the slurry were revealed as contents of TCNF increased. The green body formed from TCNF added slurry had excellent demoldability. Well-dispersed TCNF added slurry achieved stable slip cast forming process having excellent mass productivity and dense sintered bodies were obtained as a final product.
