3D printing porous zirconium oxide ceramic and preparation method thereof
The invention provides 3D printing porous zirconia ceramic and a preparation method thereof, and belongs to the technical field of advanced ceramic materials and additive manufacturing. Zirconia powder serves as a main raw material, the 3D printing zirconia porous ceramic is prepared through photocuring 3D printing and high-temperature glue discharging sintering, rapid and accurate forming of theporous zirconia ceramic can be achieved by accurately controlling the content of the zirconia powder, parameters of photocuring printing and the specific process of high-temperature glue discharging sintering, the pore channel structure is controllable, and ceramic products with complex structures and shapes can be prepared; the method does not need a mold, a pore-forming agent or a pore-forming template, and is low in preparation cost and high in production efficiency. The 3D printing porous zirconium oxide ceramic product prepared by the method is good in mechanical property, high in porosity, thin in pore wall, large in surface area and high in pore passage connectivity, and can be widely applied to the industrial field as a filter, a catalyst carrier, a heat exchanger, a heat accumulator, a bone tissue engineering bracket and the like.
