A ceramic slurry with a solid content of 57% (in volume fraction) was firstly prepared with α-Al2O3 of 92% (mass fraction) and silica fume of 8% as main raw materials, aluminum dihydrogen phosphate of 2.5% as a binder and sodium hexametaphosphate of 0.2% as a dispersant in the presence of Y2O3, and then the formed specimen was sintered at 1 600 ℃ for 3 h. The results show that the addition of Y2O3 has little effect on the printing properties of ceramic slurry. At high temperatures, Y2O3 reacts with Al2O3 to form YAG, and promotes the reaction of Al2O3 with SiO2 in the specimen, thus increasing the specimen strength. A rate of the properties change after sintering decreases, and even the slag resistance decreases when the amount of Y2O3 addition exceeds 1.2%. The cold compressive strength is 230.2 MPa at the optimal amount of Y2O3 addition of 1.2%. For slag resistance, in addition to the densification of the high melting point YAG phase and the solid phase, a dense protective layer is formed on the inner wall of the crucible, thus enhancing the resistance to the penetration of glass melt. It is indicated that the addition of Y2O3 is beneficial to printing the specimens with a high strength and a good slag resistance.
