Method for preparing zirconia ceramic by using multi-time sintering process
The invention discloses a method for preparing zirconia ceramic by utilizing a multi-time sintering process, and relates to a preparation method of ceramic. The invention aims to provide the method for preparing the zirconia ceramic by using the multiple sintering process, which has finer crystal grains and more excellent mechanical property and hydrothermal aging resistance. The method for preparing the zirconia ceramic by using the multi-time sintering process comprises the following steps: S10, preparing zirconia powder by using a hydrothermal method; s20, mixing the zirconium oxide powder with water and a dispersing agent to prepare slurry, carrying out molding treatment on the slurry, and sequentially carrying out granulation, molding, glue discharging and sintering to obtain primary ceramic; s30, the primary ceramic is heated to 1250-1400 DEG C for first sintering, and the temperature is reduced to 900-1100 DEG C; s40, the ceramic treated in the step S30 is heated to 1250-1400 DEG C for secondary sintering, and the temperature is reduced to 900-1100 DEG C; and S50, repeating the second sintering process for third and fourth sintering to obtain the zirconia ceramic.
