The results of preliminary experimental studies concerning the prevention of the leaching of heavy metals from fly ash by vitrification are presented in the paper. The problem considered relates to the potential utilisation of fly ash in water treatment. The laboratory studies were performed using the plasma method of vitrification. The fly ash used was collected from thermal power plants: firing lignite and hard coal. Soluble salts of four heavy metals (cadmium, chromium, lead and zinc) were used for doping the fly ash. Leachability of the heavy metals used from fly-ash samples and from the products of vitrification was examined according to Polish regulations. The possibility of improvement of mechanical properties of vitrification products by heat treatment was considered. Crystallisation of minerals in the vitrification glass was investigated using the XRD method. The effect of heat treatment was examined by hardness measurement on the glass and glass-ceramic.
