Porous ceramic and preparation method thereof
The invention relates to the technical field of porous ceramic preparation, in particular to porous ceramic and a preparation method thereof. The porous ceramic is prepared from raw materials including a component a, a foaming agent and water, the component a comprises 65 wt%-85 wt% of ceramic powder; 15 wt% to 35 wt% of ceramic precursor resin; 3 wt%-5 wt% of a catalyst; in the component a, the sum of the contents of the components is 100%, and the foaming agent comprises a surfactant, a binder and a dispersant. According to the preparation method, ceramic powder, ceramic precursor resin and a catalyst are taken as raw materials, ceramic nanowires are generated in situ through catalytic reaction, and nanowire reinforced porous ceramic with uniform pore diameter and uniformly distributed pores is prepared through a foaming method, so that the stability of the structural strength of the porous ceramic material under high porosity is realized. The nanowire reinforced porous ceramic material prepared by the method is uniform in pore size, uniform in pore distribution and high in mechanical strength.
