Preparation method of porous ceramic material for filtering high-temperature flue gas
The invention discloses a preparation method of a porous ceramic material for filtering high-temperature flue gas, and belongs to the technical field of porous ceramics. The preparation method comprises the following steps: weighing magnesium oxide, aluminum oxide and silicon oxide powder according to the stoichiometric ratio of cordierite, ball-milling and drying to obtain first ceramic powder; carrying out ball milling on the first ceramic powder, a fluxing agent and a pore forming agent, and drying to obtain second ceramic powder; and mixing the second ceramic powder with a binder, and carrying out dry pressing molding and high-temperature calcination to obtain the porous ceramic material for filtering high-temperature flue gas. According to the preparation method, the sintering temperature of the porous ceramic can be effectively reduced, the production cost is reduced, and the filtering resistance is reduced.
本发明公开了一种高温烟气过滤多孔陶瓷材料的制备方法，属于多孔陶瓷技术领域。所述制备方法包括步骤如下：将氧化镁、氧化铝、氧化硅粉按照堇青石化学计量比称量、球磨、干燥后，得到第一陶瓷粉体；将所述第一陶瓷粉体与助熔剂、造孔剂球磨、干燥后，得到第二陶瓷粉体；将所述第二陶瓷粉体与粘结剂混合，经过干压成型以及高温煅烧，得到高温烟气过滤多孔陶瓷材料。所述制备方法能够有效降低多孔陶瓷烧结温度、降低生产成本、减小过滤阻力的问题。
