[0026] Such as figure 1 Shown, the preparation method of the zirconia ceramics of one embodiment, comprises the following steps:
[0027] Step S110: providing ceramic powder.
[0028] Among them, in terms of mass percentage, the ceramic powder is composed of the following components: 94% to 96% of zirconia, 3.5% to 5% of yttrium trioxide, 0.2% to 1% of aluminum oxide and 0.05% %~0.2% titanium dioxide.
[0029] Among them, the median particle size of zirconia (D 50 ) is 0.1 micron to 0.5 micron. If the particle size of zirconia is too large, it will easily lead to a large grain size, which is not conducive to improving the strength and toughness. If the particle size of the powder is too fine, the powder is likely to agglomerate and generate air bubbles, which is not conducive to the preparation of gel casting slurry, resulting in more defects in gel casting molding. Zirconia with this particle size is conducive to the formation of a relatively stable and uniform slurry, w...
Embodiment 1
[0055] The preparation process of the ceramic plunger of the present embodiment is as follows:
[0056] (1) Provide ceramic powder. According to the mass percentage, the ceramic powder is composed of the following components: 96% zirconia, 3.5% yttrium oxide, 0.4% aluminum oxide and 0.1% titanium dioxide , wherein the median particle size of the zirconia is controlled to be 0.1 micron to 0.5 micron.
[0057] (2) dissolving the organic monomer and cross-linking agent in deionized water to obtain a premix; adding the premix to a ball mill tank, then adding ceramic powder, dispersant and plasticizer to ball mill for 22 hours to obtain a premix; Pour the primary mixture into a container, vacuum defoam for 60 minutes, stir and add catalyst and initiator to obtain slurry. Among them, the organic monomer is acrylamide, and the mass ratio of the organic monomer to the ceramic powder is 4:100; the cross-linking agent is N,N-dimethylacrylamide, and the mass ratio of the cross-linking a...
