Porous ceramic, preparation method thereof and atomization device
The invention provides porous ceramic, a preparation method thereof and an atomization device, and relates to the technical field of ceramic materials. The preparation method of the porous ceramic comprises the steps of preparing a ceramic aggregate, preparing the ceramic aggregate into a ceramic green body, and preparing the ceramic green body into the porous ceramic through a sintering process, the step of preparing the ceramic aggregate comprises the step of mixing a first framework material, a second framework material, glass powder and a bridging agent, and the ratio of the particle size of the first framework material to the particle size of the second framework material is 2-4. The ceramic aggregate is prepared by mixing two framework materials with the particle size ratio of 2-4 with the glass powder and the bridging agent, and the framework materials utilize a bridging mechanism that a one-dimensional material is prepared by a micro-nano-scale particle size matching method, so that the aggregate lap joint has certain strength, and continuous through holes are formed; the bridging agent can adjust the heat conductivity coefficient and flatness of the ceramic, the problems of cracking, deformation and the like of the ceramic in the subsequent sintering process are prevented, and the glass powder can serve as a binder to be in lap joint with the framework material or the bridging agent to form gaps.
本申请提供一种多孔陶瓷及其制备方法和雾化装置，涉及陶瓷材料技术领域。多孔陶瓷的制备方法包括制备陶瓷骨料、将陶瓷骨料制成陶瓷生坯、及通过烧结工艺将陶瓷生坯制成多孔陶瓷，其中制备陶瓷骨料的步骤包括将第一骨架料、第二骨架料、玻璃粉和搭桥剂混合，第一骨架料与第二骨架料的粒径的比值为2‑4。本申请采用粒径比值为2‑4的两种骨架料与玻璃粉和搭桥剂混合制备陶瓷骨料，其中的骨架料利用微纳尺度大小粒径搭配法制备一维材料桥接的机理，使得骨料搭接具备一定的强度，并形成连续贯通孔，搭桥剂可调整陶瓷的导热系数、平整度，防止陶瓷在后续的烧结过程中出现开裂、变形等问题，玻璃粉可作为粘结剂搭接骨架料或架桥剂形成空隙。
