| 摘 要： | 研究了铝盐沉淀法制备假-水软铝石过程中各因素对水合产物物性的影响规律。提出了制备低堆比的高纯假-水软铝石的方法。用NH4HCO3或(NH4)2CO3溶液做洗涤介质有效降低了假-水软铝石中的杂质含量。采用加入晶种的方法制备了低堆比、含有大孔的假-水软铝石。 |
| 关 键 词： | 铝盐沉淀法 制备 低堆比 假-水软铝石 晶种 |

| Abstract: | The effects of factors on hydrated products in the preparation of pseudo - boehmite by aluminum salt precipitation was studied.A method of preparing low bulk density and extremely pure pseudo - boehmite was introduced. Washing by NHtHCO3 or (NH4)2CO3 solution decreased the impurity in pseudo - boehmite significantly.The low bulk density and large porous pseudo - boehmite was obtained by the addition of crystal seeds. |
| Keywords: | pseudo - boehmite low bulk density aluminum salt crystal seed preparation |
