Porous ceramic particle with radial pore structure as well as preparation method and application of porous ceramic particle

The invention provides a porous ceramic particle with a radial pore structure and a preparation method and application thereof, and belongs to the technical field of porous ceramic materials. The preparation method of the porous ceramic particles comprises the following steps: (1) putting sodium alginate and calcium phosphate powder into water, and uniformly mixing to obtain calcium phosphate/sodium alginate slurry; (2) mixing the slurry with hydrogen peroxide to prepare mixed slurry; (3) preparing a mixed aqueous solution system of soluble divalent cations and catalase as a cross-linking solution; (4) dropwise adding the mixed slurry into a cross-linking solution for cross-linking, curing to form composite ceramic microspheres, washing the composite ceramic microspheres, and drying; and (5) sintering the composite ceramic microspheres dried in the step (4), and cooling to room temperature to obtain the composite ceramic microspheres. The preparation method is simple in process, additives such as sintering ai
