- 論文の詳細を見る
Chrysotile (Mg3Si2O5(OH)4) was treated hydrothermally in acid or alkaline hydroxide solution. By hydrothermal treatment in 1 M HCl, HNO3 or H2SO4 solution at 180°C for 48 h chrysotile changed to amorphous silica by complete extraction of magnesium component and its fibrous morphology was held in spite of changing chemical composition. The maximum specific surface area (SBET) of the fiberous amorphous silica was 127 m2/g. It was converted to Mg(OH)2 by complete dissolution removal of silica component in 20 M NaOH or KOH solution at 180°C for 48 h and the fiberous morphology of chrysotile disappeared.
