摘　　要：本文采用水热法以活性氧化铝为原料制备了拟薄水铝石,结合SEM,XRD,BET等分析和表征手段,着重考察了酸性、碱性和中性条件对产物性质的影响。碱性条件制备的拟薄水铝石具有最大比表面、孔容和孔径;酸性条件得到针状团簇体粉末;中性条件得到大颗粒的拟薄水铝石粉体。Hydrothermal synthesis methods were employed to pseudoboehmite from activated alumina,and the effects of different pH values on pseudoboehmite were studied with the characterization of SEM,XRD and BET.The pseudoboehmite prepared under alkaline condition had the largest surface area,pore volume and pore diameter.The pseudoboehmite powder as spicule cluster was obtained under acidic condition and the powder as granule cluster was obtained under neutral condition.
