| Abstract: | Nanosized-pseudoboehmite powder was prepared by the RBHC-high gravitational reactive carbonation method from sodium aluminates solution and dioxide.Mechanism and process of the formation of pseudoboehmite were introduced.The influence of adding surface modifier,concentration of reactant and ratio of gas/liquid flow rate on pseudoboehmite particle size in the preparation was researched.The product was characterized by TEM.The prepared particles are pseudoboehmite nano-fibers with average diameter about 5 nm. |
