The melting treatment of the incineration residuals (bottom and fly ashes) is an effective method to stabilize the toxic substances (heavy metal, DXN etc.) and to reduce the volume and weight of them for landfill. The ashes had been melted at 1873K. As a result, the bottom ash was separated into slag and metal phases. As for the fly ashes, only slag phase was generated. It was shown that these slags consisted of many kinds of components. Among them, CaO, SiO2, and Al2O3 were major components.<BR>As the first step to control the melting treatment processes, the viscosities of slags generated by melting treatment and the effects of basicity on viscosities of synthesis CaO-SiO2-Al2O3 (Al2O3=20mass%) melts had been studied by a crucible-rotating method. The higher basicities of the slags were, the lower the viscosities of them were. The effects of additives on viscosities of synthesis CaO-SiO2 (CaO/SiO2=l) and CaO-SiO2-Al2O3 (CaO/SiO2=l) melts also have been studied. The addition of Al2O3 lead to increase the viscosities of CaO-SiO2 (CaO/SiO2=l) melts, and the viscosities of the melts decreased with the addition of the other elements. The addition of fourth component (MgO, TiO2 and Fe2O3) lead to decrease the viscosities of CaO-SiO2-Al2O3 (CaO/SiO2=l) melts.<BR>More systematic studies about the effects of fourth component on viscosities of CaO-SiO2-Al2O3 melts of constant Al2O3 content will be desired.
