【摘要】 在不同成胶条件下利用铝酸钠溶液和硝酸制备了拟薄水铝石 ,研究了 pH值、成胶温度、铝酸钠浓度及成胶时间的影响 .结果表明不同的成胶条件对产物的物性有较大影响 .在合适的成胶条件下 ,可以制得纯净的拟薄水铝石沉淀 ;在一定的范围内可通过调节实验参数等来控制拟薄水铝石物化性质如堆密度、比表面积、孔容积、孔径等更多还原

【Abstract】 Pseudo?-boehmite was prepared with nitric acid and sodium aluminate under different precipitation conditions.The influences of pH concentration of sodium aluminate,precipitation temperature and time were investigated.It is shown that the precipitation conditions have great influences on product properties.Pure pseudo?-boehmite can be obtained under proper conditions.In the given range,a variety of pseudo?-boehmite with different properties such as bulk density,pore volume,surface area and pore diameter can be prepared.更多还原
