| 内容記述 | There are two kinds of the volcanic ashes from Mt.Sakurajima, Kagoshima prefecture, namely "black ash" and "grey ash." Grading analysis, chemical analysis, alkaline and acid solubility tests, X-ray analysis, physical tests and optical observation were conduced on these ashes. Moreover, alkaline solubility tests, determination of specific gravities, absorption tests of water and dye were made on these samples at various temperatures from 200°C to 1200°C. And the result is as follows : - (1) The main difference between "black ash" and "grey ash" is considered in the amount of colored rock forming mineral species, such as magnetite and hypersthene. The black ash contains more amount of these minerals than grey ash. (2) Chemical composition of volcanic ash from Mt.Sakurajima is 0.84~1.30% Ig. loss, 60.66~64.01% SiO_2, 15.36~17.54% Al_2O_3, 7.03~7.52% Fe_2O_3, 0.68~1.15% TiO_2, 1.74~1.85% CaO, 2.01~2.84% MgO, 2.47~2.91% Na_2O, and 1.74~1.85% K_2O. (3) Absorption of water and dye, alkaline and acid solubility of volcanic ash shows very small compared with volcanic glass in Shirasu. (4) Absorption of methylen blue in the water by volcanic glass in Shirasu is 465 mg/g sample at room temperature and recognized abrupt decrease of dye absorption at 600°C. |
