Tape casting method of mullite porous ceramic material
The invention discloses a tape casting method of a mullite porous ceramic material, and relates to the technical field of porous ceramic forming methods. The tape casting method of the mullite porous ceramic material comprises the following steps: uniformly mixing SiO2-Al 2O3 hollow microspheres and a sintering aid, then adding a dispersing agent, a plasticizer, a binder and water into the mixture, and uniformly stirring to obtain slurry; carrying out tape casting on the slurry to obtain a ceramic green body; dumping and sintering the ceramic green body to obtain the mullite porous ceramic material; the slurry is prepared from the following components in percentage by mass: 40 to 50 percent of SiO2-Al2O3 hollow microspheres, 9.5 to 20 percent of a sintering aid, 0.5 to 2.5 percent of a dispersing agent, 1 to 3 percent of a binding agent, 1 to 3 percent of a plasticizer and the balance of water. The tape casting method disclosed by the invention is simple in process and high in efficiency, the SiO2-Al < 2 > O < 3 > hollow microspheres are used for self-foaming pore-forming in the operation process of the method, a foaming agent does not need to be added, an inorganic pore-forming agent is selected, pollution can be reduced, the cost is saved, and the operation process of the method is more environment-friendly.
本发明公开了一种莫来石多孔陶瓷材料的流延成型方法，涉及多孔陶瓷成型方法技术领域。莫来石多孔陶瓷材料的流延成型方法，包含以下步骤:将S iO2‑Al 2O3空心微珠、助烧剂混匀，然后向其中加入分散剂、增塑剂、粘结剂和水搅拌均匀，得到浆料；将浆料流延后，得到陶瓷生坯；陶瓷生坯经排胶、烧结，得到莫来石多孔陶瓷材料；以质量分数计，所述浆料由以下成分组成：S iO2‑Al2O3空心微珠40‑50wt％，助烧剂9.5‑20％，分散剂0.5‑2.5wt％，粘结剂1‑3wt％，增塑剂1‑3wt％，水余量。本发明的流延成型方法工艺简单、效率高，方法操作过程中使用S iO2‑Al 2O3空心微珠自发泡成孔，无需外加发泡剂且选用无机造孔剂，既能够减少污染、节约成本、使方法操作过程更加环保。
