説明
Morphology of boehmite crystals hydrothermally synthesized from gibbsite in metal acetate solutions at 200°C were studied in connection with the chemical species in the hot solutions. In acetate (MAc<SUB>2</SUB>) solutions where cations were large-sized, plate-like boehmite crystals were formed (M = Ba, Sr, Ca). On the other hand, columnar crystals were produced in MAc<SUB>2</SUB> solutions where M were comparatively small-sized cations (M = Mg, Mn, Co). It was assumed that when highly stable cationic complexes between metal and acetate ions were absorbed on growing boehmite crystals, they blocked the access of AlO2- and eventually regulated the crystal morphology to from columnar crystals. Formation of not columnar but plate-like boehmite crystals observed in the cases of synthesis in rare-earth acetate (REAc<SUB>3</SUB>) solutions was explained in terms of the low blocking ability of electrically neutral REAc<SUB>3</SUB> species resulting from its weak absorption on the crystal surfaces.
