Method for preparing porous ceramic green body by combining microemulsion with freeze drying
The invention relates to a method for preparing a porous ceramic green body by combining microemulsion with freeze drying. The method comprises the following steps: (1) mixing water, an oil phase anda surfactant to obtain an oil-in-water emulsion, wherein the oil phase is preferably selected from at least one of cyclohexane, n-octane, diphenylmethane and cyclopentane; (2) adding ceramic powder, asintering aid, a dispersing agent and a binder into the obtained oil-in-water emulsion, and mixing to obtain ceramic slurry; and (3) carrying out vacuum degassing on the obtained ceramic slurry, pouring the ceramic slurry into a mold, and carrying out freeze curing and freeze drying to obtain the porous ceramic green body.
本发明涉及一种微乳液结合冷冻干燥制备多孔陶瓷坯体的方法，包括：（1）将水、油相和表面活性剂混合，得到水包油乳液，所述油相优选选自环己烷、正辛烷、二苯基甲烷和环戊烷中的至少一种；（2）在所得水包油乳液中加入陶瓷粉体、烧结助剂、分散剂和粘结剂，混合后得到陶瓷浆料；（3）将所得陶瓷浆料经真空脱气后倒入模具中进行冷冻固化和冷冻干燥，得到所述多孔陶瓷坯体。
