Method for preparing infrared radiation ceramic with high thermal shock resistance by slip casting method
The invention discloses a method for preparing infrared radiation ceramic with high thermal shock resistance by adopting a slip casting method, which comprises the following steps: dispersing 50-80 parts by mass of cordierite powder, 20-30 parts by mass of aluminum oxide powder, 1-20 parts by mass of andalusite powder, 1-20 parts by mass of kaolin powder, 1-10 parts by mass of sintering aid, 1-10 parts by mass of rare earth modified additive and 1-10 parts by mass of dispersing agent into 100-200 parts by mass of solvent; performing ball milling to obtain uniform ceramic slurry; and filtering the ceramic slurry through a screen to remove impurities. And performing slip casting on the plaster mold by a high-pressure ceramic slip casting machine to obtain an infrared radiation ceramic green body. And finishing the green body with certain hardness by using tools such as a knife, a towel and the like, so that the green body reaches a smooth standard. And after drying, pre-sintering and sintering to obtain the infrared radiation ceramic. The infrared radiation ceramic sample obtained by the preparation method has high thermal shock resistance and is easy to control, the preparation method is simple and easy to operate, raw materials are easy to obtain, and full utilization of resources is realized.
本发明公开了一种采用注浆成型法制备高抗热震性红外辐射陶瓷的方法，按质量份将50～80份的堇青石粉末、20～30份的氧化铝粉末、1～20份的红柱石粉末、1～20份的高岭土粉末、1～10份的烧结助剂、1～10份的稀土改性添加剂和1～10份的分散剂分散于100‑200份的溶剂中，球磨制成均匀的陶瓷浆料；将陶瓷浆料经过筛网过滤，去除杂质。在高压陶瓷注浆机向石膏模具注浆成型得到红外辐射陶瓷生坯。使用小刀、毛巾等工具对具有一定硬度的生坯进行修整，以使坯体达到光滑的标准。干燥后先进行预烧结、烧结、得到红外辐射陶瓷。由本发明制备方法得到的红外辐射陶瓷样品具有高抗热震性且易控制，制备方法简单易操作，原材料易得，实现了资源的充分利用。
