| 内容記述 | Xonotlite was synthesized under various conditions from amorphous siliceous rocks produced at Makizono (Kagoshima Pre.), Beppu (Oita Pre.), and Iojima (Kagoshima Pre.) which had some connection with volcanic action. The rocks of Makizono and Beppu consisted of amorphous silica and siliceous rock of Iojima are consisted essentially of amorphous silica but accompanied with cristobalite, tridymite and chalcedony. The mixture of the rocks ground, lime and water was stirred and treated hydrothermally in an autoclave under the following conditions ; molar ratio of CaO/SiO_2 1.0～1.2, weight ratio of water/total-solid 5, pressure 10～30 kg/cm^2, temperature 180～234°C, during for 5～10 hrs. It was found that the best conditions for synthesis of xonotlite in this experiment was as follows ; molar ratio of CaO/SiO_2 1.0～1.2, pressure 30 kg/cm^2, temperature 234°C, for 10 hrs. The crystals obtained were composed essentially of xonotlite and accompanied with small amount of tobermorite. The spherical aggregates of needle-like xonotlite was observed. The addition of small amount of xonotlite to the starting raw material promoted the synthesis of xonotlite. The siliceous rock of Iojima was better material for the synthesis of xonotlite than the others investigated. |
