Phase Equilibria in the BaO-SiO_2-Al_2O_3 Ternary System at 1500°C

摘要

Phase equilibria of the BaO-SiO_2-Al_2O_3 ternary system was experimentally investigated using a quenching technique and analyzed by Scanning Electron Microscopy (SEM) equipped with Energy Dispersive Analysis (EDS) and X-ray Powder Diffraction (XRD). A ternary compound was confirmed in the present work. The liquid's composition in equilibrium with the ternary compound at 1500°C were quantified. The isothermal sections of the BaO-SiO_2-Al_2O_3 ternary system at 1400°C, 1500°C, 1600°C, and 1700°C were calculated. Based on the data acquired, the isothermal section at 1500°C was constructed.
