Abstract
The present invention belongs to the field of material technology, and provides a method for configuring a zirconium oxide photocurable ceramic slurry, including pre-preparation of a liquid phase, mixing of a solid phase and a liquid phase, and optimizing the particle size ratio of ceramic particles to improve the rheological properties and stability of the slurry. The preparation process is: according to the optimized ratio, zirconium oxide powders with average particle sizes of 1 μm and 0.1 μm are mixed in a mass ratio of 3:1 to prepare a solid phase for standby use, resin monomers and photoinitiators are mixed uniformly by magnetic stirring under a constant temperature environment to prepare a liquid phase, and the solid phase, liquid phase and dispersant are ball-milled and mixed according to a solid phase content of 60wt%, to obtain a zirconium oxide photocurable ceramic slurry with good rheological properties and stability. The method of the present invention optimizes the binary particle size matching to achieve better rheological properties and stability of the zirconium oxide ceramic slurry, while not affecting its own curing characteristics, and can better meet the needs of photocurable 3D printed ceramic parts.
