The invention relates to a ceramic pug of a thin-wall plate ceramic support body. The ceramic pug comprises the following raw materials in percentage by mass: (1) solid raw materials: 60-80% of alumina powder, 10-30% of a sintering aid and 10-30% of a pore-forming agent; (2) the liquid raw materials: 15%-25% of a dispersing agent, 5%-15% of a lubricating agent and 60%-80% of pure water; wherein the weight ratio of the solid raw material to the liquid raw material is (5-7.5): 1; and the ceramic pug can be used for preparing the thin-wall flat plate ceramic support body. By adopting the method disclosed by the invention, the reject ratio of a flat sheet membrane biscuit in extrusion, drying and sintering processes can be reduced to a greater extent, and the qualification rate of the flat ceramic membrane support body is improved; the sintering temperature of the prepared flat membrane support body is greatly reduced, the production energy consumption is reduced, the chemical compositionpurity of the support body is high, and the corrosion resistance is strong.
本发明的一种薄壁平板陶瓷支撑体的陶瓷泥料，包括以下原料：（1）固体原料为包括以下质量分数的原料：氧化铝粉：60%～80%，烧结助剂：10%～30%，造孔剂：10%～30%；（2）液体原料为包括以下质量分数的原料：分散剂：15%～25%，润滑剂：5%～15%，纯水：60%～80%；所述固体原料与所述液体原料的重量比为（5～7.5）：1；采用该陶瓷泥料可以制备出薄壁平板陶瓷支撑体。采用本发明的方法能更大程度降低平板膜素坯在挤出、干燥、烧结过程中不合格率，提高平板陶瓷膜支撑体的合格率；制得的平板膜支撑体烧结温度大大降低，生产能耗降低，且支撑体的化学组成纯度高，其耐腐蚀性能强。
