Glass-ceramics from filter dusts from waste incinerators

Glass-ceramics: Their production from wastes—A Review

“…The present review is concerned with reuse of waste materials to produce glass-ceramics. The versatility of the glass-ceramic production process is manifested by the many wastes that have been used as raw materials for glass-ceramics, which include coal fly ash [30][31][32][33], mud from zinc hydrometallurgy [34][35][36][37], slag from steel production [13,[38][39][40][41][42][43], ash and slag from waste incinerators [44][45][46][47][48][49][50][51][52][53][54][55][56][57], red mud from alumina production [58], waste glass from lamp and other glass products [59] as well as electric-arc furnace dust and foundry sands [60]. Much work has been carried out on the immobilisation of nuclear waste in glass and ceramic matrices and recently there has been some interest in the use of glass-ceramic matrices for this purpose [61,62].…”

El proceso de vitrificación/cristalización controlada aplicado al reciclado de residuos industriales inorgánicos

“…Recent investigations have proposed the use of these wastes in several applications, viz., fabrication of building materials (3), catalysts and pigments (4), refractories (5), puzzolanic material (6) and glass-ceramic materials (7). This paper reports the results obtained by the authors in the last years in the processing at high temperature of industrial wastes (red muds from zinc hydrometallurgy, fly-ashes from thermal power stations, fly-ashes and slags from domiciliary incinerators) to produce glassy and glass-ceramic materials with useful properties to be used as building materials.…”

“…En este sentido se han propuesto numerosas soluciones como el uso de estos residuos como materiales de construcción (3), catalizadores y pigmentos (4), refractarios (5), material puzolánico (6) y materiales vitrocerámicos (7).…”

Surface and Bulk Crystallization of Glass‐Ceramic in the Na2O‐CaO‐ZnO‐PbO‐Fe2O3‐Al2O3‐SiO2 System Derived from a Goethite Waste

“…The glass-ceramic process has already been applied for recycling of other wastes such as coal fly ashes, 8,9 fly ashes from urban waste incinerators,10,11 and nuclear wastes.…”
