[0036] The preparation method of above-mentioned yttrium stabilized zirconia slurry comprises the following steps:
[0037] Step S110, mixing the yttrium-stabilized zirconia powder, water, powder modifier, film-forming agent, defoamer, dispersant and thickener, and then ball milling for 12-24 hours to obtain a premix.
[0038] Step S120, adding neutralizer and binder into the premixed material and continuing ball milling for 12-24 hours to obtain yttrium-stabilized zirconia slurry.
[0039] Preferably, after preparing the yttrium-stabilized zirconia slurry, use a 325-mesh filter cloth to filter, and test the viscosity, solid content and density of the yttrium-stabilized zirconia slurry, and then place the yttrium-stabilized zirconia slurry in the slurry pot Grind medium and slow for later use.
[0040] The above-mentioned preparation method of the yttrium-stabilized zirconia slurry has simple operation.

Embodiment 1
[0051] 1. Prepare materials according to Table 1.
[0052] Table 1
[0053]
[0054] 2. Put YSZ powder, ultrapure water, powder modifier, film-forming aid, defoamer, dispersant, and thickener into a ball mill tank, and ball mill for 12 hours;
[0055] 3. Add the neutralizer and binder into the ball mill tank, and ball mill again for 12 hours;
[0056] 4. After the ball milling is completed, use a 325-mesh filter cloth to filter the output, and test the viscosity, solid content and density of the slurry. After completion, seal the yttrium-stabilized zirconia slurry and place it in a slurry pot for slow grinding for later use;
[0057] 5. Using PET film casting, the casting thickness is 150μm, and the drying temperature of the first to fifth temperature zones are: 60°C, 90°C, 120°C, 140°C, 80°C.
[0058] The viscosity of yttrium-stabilized zirconia slurry is tested by NDJ rotational viscometer, the solid content is tested by burning method, and the density is tested by dens...
