Resumo
The vitrification process is an attractive route for the inertization treatment of hazardous
industrial wastes. The corrosion resistance of this kind of materials is one of the most important
requirements to ensure the long term retention of the toxic metals. In this work, silicate glasses with
various waste concentrations were obtained using a galvanic sludge from metallurgical activities
and glass forming rejects from ceramic activities. Glasses with several galvanic waste
concentrations were obtained. The corrosion behaviour of the vitrified materials under various pH
media was evaluated. The FTIR technique was used to investigate the glass structural
modifications. Glasses containing 40 wt.% galvanic waste additions show higher resistance to
corrosion media than those without waste additions.
