研究了溶剂、机械研磨的三水铝石和无定形水合氧化铝凝胶对结晶良好和亚微米尺寸的勃姆石晶体形成的影响。将球磨的三水铝矿在水中于 200°C 下水热合成 6 小时，得到近似单分散的平行四边形形状的 0.2-0.3 μm 勃姆石颗粒。 100 nm 大小的勃姆石晶体由无定形水合氧化铝凝胶在 255°C 24 小时制备。
The effect of solvents, mechanically ground gibbsites and amorphous hydrated alumina gels on the formation of well-crystallized and submicrometer-sized crystals of boehmite was studied. Nearly monodispersed boehmite particles of 0.2–0.3 μm with a parallelogram shape were hydrothermally synthesized from ball-milled gibbsite in water at 200°C for 6 h. The 100 nm-sized crystals of boehmite were prepared from amorphous hydrated alumina gels at 255°C for 24 h.
