Zirconia ceramic preparation method and zirconia ceramic identification card
The invention relates to a zirconia ceramic preparation method and a zirconia ceramic identification card, and the zirconia ceramic preparation method comprises the following steps: adding 91-92% by mass of zirconia powder, 0.3-0.5% by mass of alumina powder, 4.2-4.6% by mass of yttrium oxide powder and 3.3-3.9% by mass of ceramic toner powder into a mixing barrel, uniformly mixing, adding the uniformly mixed powder and water into a ball mill according to a ratio of 1: (0.4-0.7), adding a dispersing agent, uniformly mixing, and carrying out ball milling to obtain the zirconia ceramic identification card. The preparation method comprises the following steps: adding PVA (polyvinyl alcohol) into a ball mill to obtain primary slurry with the solid content of 30-50%, granulating and spraying the primary slurry, calcining at 900-1050 DEG C to obtain a primary calcined material, adding the primary calcined material and water into the ball mill according to the ratio of 1: 0.3-0.5, adding a dispersing agent, uniformly mixing to obtain secondary slurry with the solid content of 60-70%, slowly adding PVA, uniformly stirring, granulating and spraying, carrying out compression molding, pressing under isostatic pressing, degreasing and sintering a blank, thereby obtaining the PVA-PVA composite material. The zirconia ceramic with high bending resistance is prepared.
