摘　　要：分别用纳米γ-Al_2O_3和SB粉制备了多孔陶瓷载体的Al_2O_3涂层。BET法测定了多孔陶瓷载体Al_2O_3涂层改性前后比表面积的变化。由SEM照片观察多孔陶瓷载体涂层改性前后表面和断面的形貌。结果表明,这两种方法对多孔陶瓷载体涂层改性均有效可行。Modification of porous ceramic surface by preparing alumina coating with nanoparticle γ-Al2O3 or SB powder ( a powder with boehmite-like crystal form), respectively, was studied. Characterization using surface area measurement and the SEM photographs of the surface and cross-section of the ceramics with alumina coating showed that both methods for preparation of alumina were successful in modification of ceramic surface.
