Method for preparing porous alumina ceramic through sucrose pore-forming
The invention provides a method for preparing porous alumina ceramic by sucrose pore-forming, which comprises the following steps: (1) weighing alumina powder, sucrose and magnesium oxide powder in proportion, and mixing to obtain a ceramic raw material; (2) adding absolute ethyl alcohol and grinding beads into the ceramic raw material, and carrying out wet ball milling; (3) taking out the ball-milled material, and fully drying to obtain a mixture; (4) adding an adhesive into the mixture, and uniformly mixing; (5) performing dry pressing on the material in the step (4) to obtain a ceramic blank; (6) fully drying the ceramic blank; and (7) sintering the dried ceramic blank to obtain the porous alumina ceramic.
本发明提供了一种蔗糖造孔制备多孔氧化铝陶瓷的方法，包括如下步骤：(1)将氧化铝粉、蔗糖、氧化镁粉按比例称量后混合，得到陶瓷原料；(2)在陶瓷原料加入无水乙醇和研磨珠，实施湿法球磨；(3)经球磨后的物料取出后充分干燥，得到混合料；(4)在混合料中加入粘接剂并混均；(5)对步骤(4)中的物料进行干压成型，得到陶瓷坯材；(6)陶瓷坯材充分干燥；(7)干燥后的陶瓷坯材烧结，得到多孔氧化铝陶瓷。
