- Abstract
Recycling/reusing industrial waste materials in ceramic products has been a trending research topic in recent decades due to its economic and environmental impacts. The metallurgical by-products are common waste materials that are investigated in the production of ceramics, glasses, and glazes. In this research, a spent iron oxide powder obtained from iron and steel production is selected and investigated as an alternative material for forming aventurine glazes. The selected waste iron oxide material ADO was previously physically processed to remove metal pieces and large agglomerate to obtain a uniform homogenous powder. The ADO powder was then characterized by XRF, XRD, and DTA/TG techniques to investigate the chemical composition, phase structure, and thermal behavior. The characterization of ADO powder revealed that it contains more than 95 wt% Fe2O3 with a significant constitutional phase of hematite. In the second step, the effect of ADO was investigated on the physical, phase, and microstructural properties of aventurine glazes by adding 10-30 wt% in the recipes. The glazes were prepared by wet milling and applied on the surfaces of 980oC pre-fired ceramic plates. And then fired at 1100 °C for 30 min. As a result of the visual examination of the surfaces, it was observed that the produced aventurine glazes exhibited a homogeneous formation and there were no glaze defects such as cracks or unreacted areas. Anorthite, lithium aluminum silicate, quartz, cristobalite, lithium iron zinc oxide, lithium iron oxide and hematite crystals were found in the produced aventurine glazes.
