Preparation method of ceramic powder, ceramic slurry and porous ceramic
The invention belongs to the technical field of ceramic core preparation, and relates to ceramic powder, which is prepared from the following components in percentage by mass: 30 to 60 percent of ceramic aggregate, 5 to 20 percent of sintering aid, 1 to 10 percent of glass powder and 10 to 50 percent of pore forming agent, wherein the ceramic aggregate is composed of 20%-50% of quartz sand and 10%-30% of magnesium oxide. The invention also relates to a ceramic slurry and a preparation method of the porous ceramic. According to the technical scheme provided by the invention, the uniformity of the ceramic powder can be improved, the specific surface area of the ceramic is reduced, and the flowability of the ceramic slurry is good, so that the porosity and structural strength of the porous ceramic are improved.
本申请属于陶瓷芯制备技术领域，涉及一种陶瓷粉，按质量百分比计，陶瓷粉包括以下组分：30％～60％的陶瓷骨料，5％～20％的助烧剂，1％～10％的玻璃粉与10％～50％的造孔剂；其中，陶瓷骨料由20％～50％的石英砂与10％～30％的氧化镁组成。本申请还涉及一种陶瓷浆料以及多孔陶瓷的制备方法。本申请提供的技术方案能够提高陶瓷粉的均匀性，降低陶瓷的比表面积，使陶瓷浆料的流动性好，从而提高多孔陶瓷的孔隙率与结构强度。
