Porous ceramic precursor and porous ceramic
The invention discloses a porous ceramic precursor and porous ceramic, and relates to the technical field of ceramic precursor and ceramic production. The porous ceramic precursor comprises the following components in percentage by mass: 15-40% of lanthanum zirconate, 2-5% of anorthite, 2-5% of silica powder, 1-10% of hydroxypropyl starch, 1-3% of a thickening agent, 0.1-0.8% of a dispersing agent and the balance of water. The lanthanum zirconate is obtained by ball-milling and calcining a mixture of zirconium oxide and lanthanum oxide, and in the mixture of zirconium oxide and lanthanum oxide, the molar ratio of zirconium oxide to lanthanum oxide is (1.8-2.2): 1. The porous ceramic precursor disclosed by the invention is obtained by combining various effective components and matching with a special freeze-drying process, has a complex pyrochlore structure, can be used for preparing the porous ceramic, obtains the porous ceramic with a lamellar pore structure, is applied to the field of atomization cores, increases the liquid storage capacity of the atomization cores, and improves the atomization performance of the atomization cores. The porosity of the atomizing core, namely the permeability of atomized liquid, is improved, and the service life of the atomizing core is prolonged.
本发明公开一种多孔陶瓷前驱体及多孔陶瓷，涉及陶瓷前驱体和陶瓷生产技术领域。一种多孔陶瓷前驱体，以质量分数计，包含以下成分：锆酸镧15‑40％，钙长石2‑5％，硅微粉2‑5％，羟丙基淀粉1‑10％，增稠剂1‑3％，分散剂0.1‑0.8％，水余量；所述锆酸镧为氧化锆和氧化镧的混合物经球磨、煅烧后得到，所述氧化锆和氧化镧的混合物中，氧化锆和氧化镧的摩尔比为1.8‑2.2:1。本发明的多孔陶瓷前驱体，通过多种有效成分的结合，搭配特殊的冷冻干燥工艺得到，该前驱体具有复杂的烧绿石结构，可用于制备多孔陶瓷，得到具有薄片状的孔结构的多孔陶瓷，应用于雾化芯领域，增大雾化芯的储液量，提高雾化芯的孔隙率，即雾化液的渗透性，延长雾化芯的使用寿命。
