Embodiment 1
[0024] A zirconia bioceramic, comprising the following components in parts by mass:
[0025] 60 parts of zirconia, 2 parts of nano titanium oxide, 3 parts of nano β-alumina, 0.2 parts of lanthanum trichloride, 3 parts of seaweed fiber.
[0026] Prepare zirconia bioceramics according to the preparation method provided by the present invention, the steps are as follows:
[0027] (1) Weighing: Accurately weigh each component;
[0028] (2) Ball milling: Mix the components together and put them into a ball mill for grinding and mixing;
[0029] (3) Cold press forming: the mixed powder is pressed with a 60T press;
[0030] (4) Put the formed powder into the mold and perform high-temperature calcination at a temperature of 1150°C and a pressure of 600MPa for 4 hours;
[0031] (5) After calcination, it is cooled and taken out to obtain bulk zirconia bioceramics.
