摘要
The effect of solvents, mechanically ground gibbsites and amorphous hydrated alumina gels on the formation of well-crystallized and submicrometer-size crystals of boehmite was studied. Nearly monodispersed boehmite particles of 0.2-0.3 mu m with a parallelogram shape were hydrothermally synthesized from ball-milled gibbsite in water at 200 degrees C for 6 h. The 100 nm-sized crystals of boehmite were prepared from amorphous hydrated alumina gels at 255 degrees C for 24 h. (C) 2000 Elsevier Science Ltd. All rights reserved.
