The role of the melting treatment of the solid waste has become more and more important to reduce the volume of solid waste because of the lack of land fill sites. However, it is required, for the trouble-free operation of the plants, to provide the physico-chemical properties of the slag generated from the melting treatment of municipal solid waste (MSW). The purpose of this paper is to investigate the crystallization behavior of the MSW slag using Hot-Thermocouple method. Additionally, the effect of additive oxides on the crystallization behavior of the synthetic slag and the MSW slag also have been investigated. As a result, Time-Temperature-Transition curves of the crystallization MSW slag depended on the chemical composition of the slags strongly. Appearances of the quenched slags were colored and transparent glasses. Moreover, it was found that TiO2 and Li2O additives accelerated the crystallization of the slag.
