Effects of Dialysis on the Formation of Imogolite from Highly Concentrated Hydroxyaluminum-Silicate Solution

抄録

  To examine the effects of dialysis on the formation of imogolite and the stability of imogolite precursor, a highly concentrated Si and Al mixed solution was dialyzed against distilled water for several tens of hours and heated at 98°C after various time durations. Imogolite was synthesized from the solutions dialyzed for 48-108 h, irrespective of the duration, within 6 days after dialysis. For dialysis times of over 120 h, imogolite was not synthesized for the 6 day duration.
