Palabras calve: vitrocerámica, lodo depuradora, valorización, vidrio Production of glass-ceramic materials obtained from sewage sludge treatment plant for urban wastewater in El-Sadat city (Egypt). Urban wastewater security is a source of significant volumes of sludge which is to be managed. This paper presents the possibility of applying a management process based on vitrification and by which, in addition to inert contaminants in sludge, you get a ceramic material with a significant added

... e. As a base of different analysis of the sludges, chemical (XRF), mineralogical (XRD) and thermal (DTA-TG), we obtain the original glass composition and its energy. By DTA-TG, dilatometry and SEM, it was determined the temperature of maximum nucleation rate, growth temperature and the morphology and size of developed nuclei, in this case are nanoscale. Briefly, it was found as the management of municipal solid waste by vitrification as an alternative to landfills and incineration.
