Comparative studies of the corrosion and long-term stability of vitrified e-filter dust from waste incinerators, granules from high-temperature wasteincineration plants and a model glass

The objective of this study was to describe the corrosion behaviour of vitr ified residues of municipal waste incinerators by using standardized short- term and long-term leaching and corrosion test methods. The results for the vitrified product were compared to the results for granules from high-temp erature waste incineration plants and a model glass. The test methods used in this work are, on the one hand, a German and a Swiss test [I and 2] to d escribe the possibility for the disposal of waste and, on the other hand, t est methods [3 and 4] to characterize the corrosion behaviour of glass prod ucts The results according to the different methods and their changing test parameters like temperature, corrosion time and leaching solution are pres ented.
