Abstract

ZrO₂ ceramic parts were prepared by DLP technology. The effects of powder characteristics, solid-phase content and sintering temperature on the properties of the parts were studied. The results show that the optimal grinding parameters are rotation speed of 500 r/min and grinding time of 5h, and the average particle size of ZrO2 powder is 8 μm; With the increase of solid-phase content, the viscosity and fluidity of slurry increase; Increasing grinding speed and time can slow down the increase of viscosity and improve the fluidity of slurry; When the solid-phase content is 70% and the temperature is 1600℃, the effect of the sintered part is the best. With the increase of the solid-phase content, the shrinkage of the sintered part decreases and the compressive strength increases. The experimental results are verified by SEM micro morphology test.
