| 摘 要： | A novel hydrothermal process for preparation of single-phase pseudoboehmite from supersaturated sodium aluminate solution with SB pseudoboehmite seed was presented. The process is characterized by precipitation for 3 h at temperature around 125 ℃ with a seed ratio of 1.0. Precipitation yield of Al2O3 over 20% could be reached and the specific surface area of precipitated products almost as high as SB seed could be obtained. The process suitable for preparing pseudoboehmite with any pseudoboehmite seed in principle comprises a highly variation of the current Bayer process and the latest boehmite process for the production of smelter grade alumina.
