Preparation method of aluminum oxide sintered body
The invention relates to a preparation method of an aluminum oxide sintered body. The preparation method includes the steps that aluminum oxide powder, deionized water and binder rho-aluminum oxide are evenly mixed and stirred and placed in a bag, stand still for 12-15 h in a sealed mode, and are placed in a die in a filled mode and subjected to pressure maintaining for 60-150 s at the pressure of 50-80 MPa, preformed cakes are subjected to vacuum sealed packaging and then placed on an isostatic cool pressing machine for isostatic cool pressing, finally, the cakes obtained after isostatic cool pressing are placed in a microwave sintering furnace for vacuum sintering, and then the aluminum oxide sintered body is obtained. The density of the sintered body is larger than 3.75 g/cm<3>, and the purity of the sintered body is larger than 5 N. According to the method, the purity of powder can be effectively controlled, cost is low, industrial production is easy, and high practical application value is achieved.
