Abstract: This paper focuses on the dispersion of ceramic powder in photosensitive resin. The effects of powder properties, dispersant type and dosage, and solid content on the rheological properties of stereolithography ZrO2 ceramic slurry were studied. The result shows that the properties of the powder have a significant impact on the rheological properties of the slurry, the use of ZrO2 powder with a smaller specific surface area and higher sphericity is more conducive to the preparation of low viscosity and high solid content slurry. The rheological properties and stability of the slurry are mainly controlled by the type and dosage of dispersant, using X-100 with a relative powder mass of 4% as a dispersant, the rheological properties and stability of the prepared ceramic slurry are better. The experimental result of the solid content of the slurry shows that the relationship between the solid content of the slurry and the viscosity satisfies the Krieger-Dougherty model. And the dispersion mechanism of the dispersant has been studied. By the research of this experiment, the foundation has been laid for the high-precision molding of the light-cured ZrO2 ceramic slurry.
