Potential Applications of Vitrified Slag as a Product of Plasma Arc Melting

The present article presents the potential of vitrified slag, one of the products of plasma arc melting, for further industrial applications based on previous experiments. The existing publications on the investigation into this field is hence supplemented with our series of experiments conducted using vitrified slag from plasma arc gasification and melting of fly ash from municipal waste, as well as a mixture consisting of fly ash produced by fluidised-bed boilers in a heat power plant and recovered asbestos cement roofing sheets. It should be noted that the process of plasma arc gasification and melting facilitates not only a significant reduction of the quantity of processed hazardous wastes, but also a possibility of transforming such wastes into an inert product, which may be used as an input raw material in certain industrial processes
