多孔 Al2O3－ZrO2陶瓷的微观结构

摘要

The low viscosity and high stability ceramic slurry were fabricated introducing Al2 O3 and ZrO2 ceramic powder as solute ,camphene as the solvent and Texaphor963 as additives .The por‐ous Al2 O3 -ZrO2 ceramics were prepared with high strength ceramic bodies by freezing casting meth‐od ,using pressureless sintering process .The microstructures of porous Al2 O3 -ZrO2 ceramics were studied in this paper .%以Al2 O3，ZrO2陶瓷粉体为溶质，以莰烯为溶剂，以Texaphor963作为添加剂，制备出低粘度高稳定性的陶瓷浆料，采用冷冻注模工艺制备出具有较高强度的陶瓷坯体，采用无压烧结工艺，得到了多孔Al2 O3－ZrO2陶瓷制品，并对其微观结构进行了研究。
