摘　　要：以氧化铝为主要原料,采用注浆成型法制备氧化铝陶瓷弯管。论文比较详细地研究了pH值、颗粒级配和有机粘结剂对产品性能的影响。结果表明:当pH值为1,粘结剂为2wt%获得的泥浆粘度最小;用颗粒大小4μm的100%α-Al2O3细粉制备的氧化铝陶瓷弯管气孔率最小、表观密度最大、显微结构最理想。Based on aluminium oxide as main raw material, aluminium oxide ceramic-curved pipe was prepared by slip casting, pH, particle grading and binder were reshearched on the performance of aluminium oxide ceramic-curved pipe in detail.The results showed that. When the pH is 1 and binder is 2wt%, the viscosity of mud is smallest. The particle grading is 4 μ m 100% a-Al2O3 powder which porosity is the smallest, apparent density is the biggest, the microstructure is the most ideal.
