preparation example Construction
[0032] A preparation method of a ceramic material, comprising the steps of:
[0033] a) Photocuring the slurry containing the ceramic powder to obtain a green body;
[0034] b) Degreasing, impregnating and sintering the green body in sequence to obtain a ceramic material.
[0035] The invention prepares the green body through the light-curing molding method, which has high molding efficiency and high precision of the shape and size of the green body; through degreasing, the green body forms a porous green body without deformation and cracking, and after impregnation, it can realize In the case of a small amount of reinforcing phase as an additive, a ceramic material with high strength and high toughness is prepared.
[0036] In the present invention, the particle size of the ceramic powder is 0.10 μm to 10 μm.
[0037] The ceramic powder is one or more of alumina ceramic powder, zirconia ceramic powder, aluminum nitride ceramic powder and silicon nitride ceramic powder.
