| 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. |
