説明

Basicity (mainly CaO/SiO2) is often used to describe the melting characteristics of wastes, which are comprised of multiple components. Although basicity shows certain tendencies related to the melting characteristics of individual types of waste, it lacks versatility.<BR>Diagrams with SiO2, CaO, and FeO at the vertexes were depicted by slicing 14 existing types of quaternary phase diagrams with SiO2, Al2O3, CaO, and FeO on a plane at a fixed amount of Al2O3. Compared with basicity-based indications, the quaternary phase diagrams are found to be able to describe more precisely the relationships between components and melting (flowing) temperatures. Melting temperature data obtained from Russian research on the viscosity of blast-furnace slag were plotted on the diagram, indicating that their distribution patterns closely resemble those of our data. It can be said that these results confirm the effectiveness of the diagram in describing the melting characteristics of wastes.
