Yttrium oxide stabilized zirconia ceramic foam material with micron-sized layered pore structure and preparation method thereof
The invention relates to a yttrium oxide stabilized zirconia ceramic foam material with a micron-sized layered pore structure and a preparation method thereof. The preparation method comprises the following steps: firstly, preparing a mixed suspension containing yttrium oxide nano powder, zirconia nano powder, polyacrylamide and polyvinyl alcohol; and sequentially carrying out high-energy ball milling, vacuum stirring defoaming, directional solidification, freeze drying and heat treatment to obtain the yttrium oxide stabilized zirconia ceramic foam material with the micron-sized layered pore structure. Compared with the prior art, the porous yttrium oxide stabilized zirconia ceramic with a micron-sized layered pore structure is prepared by adopting a directional solidification technology and a freeze drying technology, and has the advantages of uniform structure, compact pore wall, controllable wall thickness, high porosity, excellent mechanical strength, good heat insulation effect and the like, and the ceramic has great application potential in the fields of metallurgy, chemical industry, biological medicine, aerospace crafts and the like.
