초록
The vitrification processes and characteristics of basalt stone dust were assessed for applications. X-ray diffraction(XRD) and X-ray fluorescence (XRF) confirmed that basalt stone dust was comprised of most of the mineral types of Albite,Anorthite, Aegirine, Augite, and Quartz and minor mineral types of Diopside and Forsterite. XRF showed that the SiO2, Al2O3, Fe2O3,and CaO were mainly present in the basalt stone dust. XRD and observations of the pellet showed that the basalt stone dusts began tomelt from 1200℃ to higher temperature ranges. When Borax (Na2B4O7-10H2O) was added to the basalt stone dusts, however, themelting point (MP) of the basalt stone dust system was approximately 700℃, showing more than 500℃ reduction. Therefore, it isnecessary to add Borax to basalt stone dust for the purpose of recycling as glass and energy savings.
