Preparation method of porous ceramic, porous ceramic, atomizing core and electronic atomizing device
The invention relates to the technical field of porous ceramic preparation, and discloses a preparation method of porous ceramic, the porous ceramic, an atomizing core and an electronic atomizing device. The preparation method of the porous ceramic comprises the following steps: mixing quartz powder, a sintering aid Na2SiO3, boric oxide, low-temperature glass powder, pore-forming agent floating beads and chopped quartz fibers, and carrying out mechanical ball milling to obtain mixed powder; uniformly mixing the mixed powder with a polyvinyl alcohol aqueous solution, and pressing and forming a ceramic green body by using a dry pressing method; the ceramic green body is placed in a drying oven to be dried, and a dried green body is obtained; and sintering the dried green body in a temperature-controlled box-type furnace, and naturally cooling to obtain the porous ceramic. The floating beads and silicon dioxide in the quartz powder can generate mullite whiskers on the interfaces of the chopped quartz fibers, the chopped quartz fibers also provide nucleation and growth interfaces for a liquid phase in the early and middle sintering stages of the porous ceramic, the strength and other mechanical properties of the porous ceramic can be greatly improved, meanwhile, the whiskers do not need to be added, and the production cost is reduced.
本发明涉及多孔陶瓷制备技术领域，公开一种多孔陶瓷的制备方法、多孔陶瓷、雾化芯及电子雾化装置。所述多孔陶瓷的制备方法包括如下步骤：将石英粉、助烧剂Na2SiO3、氧化硼、低温玻璃粉、造孔剂漂珠及短切石英纤维混合并进行机械球磨，得到混合粉体；将混合粉体与聚乙烯醇水溶液混匀，用干压法压制成型陶瓷生坯；将陶瓷生坯置于干燥箱内干燥，得到干燥坯体；将干燥坯体置于控温箱式炉中烧结，自然冷却后得到多孔陶瓷。漂珠可与石英粉中的二氧化硅在短切石英纤维界面生成莫来石晶须，短切石英纤维也为多孔陶瓷烧结早中期的液相提供形核和生长界面，能极大地提高多孔陶瓷的强度和其他力学性能，同时，无需添加晶须，降低了生产成本。
