| Abstract Scope |
Electrical Impedance Tomography (EIT) is a promising technique for in-situ visualization of internal structures in high-temperature molten oxides, which are crucial in pyrometallurgical processes. This presentation addresses the visualization of dissolution and crystallization phenomena. Using an alumina sphere as a simulated solid phase, EIT could capture the dissolution behavior from the change in conductivity corresponding to alumina content in the molten oxide sample. Crystallization behavior could also be detected by EIT, due to the conductivity contrast between molten oxides and solid phases. Solid phases were observed more frequently in the central region than in the outer edge. Based on the calculated phase diagram, the primary phase was identified as melilite, specifically gehlenite. These findings suggest that EIT can serve as a versatile tool for evaluating secondary phases and understanding the physicochemical properties of molten oxides in real-time, offering new insights into process optimization in high-temperature industrial environments. |
