Melting temperature of basalt
Web26 jul. 2024 · Abstract. Melting phase relations involving model carbonated basalt with excess silica were studied in experiments over the pressure range of 4–7 GPa in the system CaO-MgO-Al 2 O 3-SiO 2-CO 2 to determine if there is a sharp decrease in the melting temperatures along the transition from carbon dioxide vapor (vapor) to dolomite. The … WebThe process of melting basalt stone from Mataram Baru, East Lampung has been carried out over a mini shaft furnace with a temperature of 1600 ˚C.
