内容記述 | Shirasu volcanic glass (shorten as SVG) separated from the original Shirasu obtained in southern Kyushu has a fixed chemical composition and contains about 75% SiO_2 by weight. In this paper, SVG was assumed to be a component and the glass-forming region in the system SVG-CaO-MgO was investigated by quenching the melts produced at 1400~1500°C into cold water. The obtained SVG-CaO-MgO glass crystallized above 900°C. The crystal phases precipitated in the heat-treated SVG-CaO-MgO glass at 1100°C for 1 h were akermanite, diopside and forsterite. Physical, optical, chemical and thermal properties and bending strength of the glasses were investigated. Results are as follows : apparent density 2.67~2.76g/cm^<3>, bending strength 539~882kg/cm^<2>, hardness (D.P.H) 613~713kg/mm^<2>, refractive index 1.578~1.622 ± 0.003, thermal expansion co-efficient (room temperature~700°C) 5.9~9.3×10^<-6>/°C. The glasses showed high resistance to alkaline solution, namely the mean weight loss of the glasses which had been treated by 2N-NaOH solution at 100°C for 14 h was so small as to be 0.7%. |
