Preparation method and application of macroscopic gradient pore structure porous ceramic with Thiessen polygon characteristics
The invention relates to the field of porous materials, in particular to a preparation method and application of macroscopic gradient pore structure porous ceramic with Thiessen polygon characteristics. The method comprises the following steps: constructing geometric figures with different aperture sizes and gradient transition in a space based on a Thiessen polygon principle by utilizing three-dimensional modeling software; forming a resin template with a macroscopic gradient pore structure through photocuring 3D printing; preparing ceramic slurry, and carrying out ball milling and uniform mixing; injecting the ceramic slurry into the mold in which the resin template is placed, degassing, compacting and curing to obtain a porous ceramic green body; and carrying out pyrolysis on the green body to remove the resin template, degreasing, sintering at high temperature and the like to realize densification, thereby obtaining the porous ceramic with the macroscopic gradient pore structure. The porous ceramic has a cascade transition random pore structure, a wide volume fraction range, good geometric dimension precision and high density, efficient preparation of the macroscopic gradient pore structure porous ceramic with Thiessen polygon characteristics is achieved, and a foundation is laid for application of the porous ceramic.
