High-porosity and high-strength aluminum oxide ceramic and 3D printing preparation method thereof
The invention discloses high-porosity and high-strength aluminum oxide ceramic and a 3D printing preparation method thereof, and relates to the technical field of aluminum oxide ceramic preparation. The invention relates to a 3D printing preparation method of high-porosity and high-strength aluminum oxide ceramic. The preparation method comprises the following steps: S1, uniformly mixing aluminum oxide powder and a binder, and performing spray granulation to obtain granulated aluminum oxide powder; s2, mixing the granulated aluminum oxide powder and resin powder to form mixed powder; s3, printing the mixed powder into a ceramic body through selective laser sintering; s4, the ceramic green body is subjected to degreasing treatment, and a degreased ceramic component is obtained; and S5, sintering the degreased ceramic component to obtain the aluminum oxide ceramic with high porosity and high strength. According to the 3D printing preparation method, the strength of an aluminum oxide framework is further improved through spray granulation, SLS in 3D printing, degreasing and sintering; the steps are simple and easy to implement, and the strength performance of the alumina ceramic is greatly improved.
