| 摘 要： | 用一种含Al2O3的非晶质浆液与烧结法铝酸钠精制液以一定比例混合，使溶液具有极大的过饱和度，从而自发分解产出平均拉径在0．5μm以下、高分散性、其具有极为发达表面和甚多活性点的超细氢氧化铝晶种，以此超细氢氧化铝作晶种用种分制取粒度和化学组成都符合指标要求的超细氢氧化铝。

| Abstract: | Alumina-containing amorphous slurry and sodium aluminate green liquor from sintering process are mixed in a given proportion to produce a solution with an extreme supersaturation. Superfine aluminum hydroxide seed of less than 0.5m in average grain size, high dispersibility, high developing surface and many active points is then generated by spontaneous decomposition of the solution. The seed can be used in seed precipitation to produce superfine aluminum hydroxide qualified in grain size and chemical composition. |

| Keywords: | superfine aluminum hydroxide seed amorphous slurry caustic ratio average grain size |
