Valorization of Waste Produced in the Processes of Plating Technologies within a Vitreous Matrix

Abstract:

The paper presents the valorization of galvanic wastes with nickel content. This process consists in waste incorporation in a borosilicate glass, and the obtaining of some glasses which may be used in industry.There were prepared glasses using both wastes and natural material as raw materials.The dissolving of the samples was carried out in electric furnance at a temperature of 1400°C for three hours. The pre-roasting of the samples was accomplished at the temperature of 600°C for 25 minutes, and their cooling in the same time with the furnance. For the samples obtained the hydrolytic stability through the conductometric method and the viscosity through the penetrometric method were determined.The experimental results reveal a good chemical stability of the glasses obtained from the wastes and a viscosity that increases with the decrease of both the nickel oxide content and the temperature. Keywords: galvanic wastes, nickel, borosilicate glasses
