Preparation Of Glass-Ceramics Largely Using Steelmaking Slags And Study On The Effect Of Iron Content On Properties Of Glass-Ceramics, Huan Feng
Huan Feng
Glass-ceramics were prepared using steelmaking industry waste containing high iron content based on powder sintering and crystallization method. Anthracite was used in varying amounts as the reducing agent to recover iron in raw materials. X-ray diffraction analysis (XRD), Fourier Transform Infrared Spectroscopy (FTIR), and Scanning Electron Microscope (SEM) coupled with Energy Dispersive X-ray spectrometer (EDX) were used to study the microstructure of glass-ceramics formed. Bending strength and micro-harness of the samples were compared. When 12g of anthracite was used, ionic iron (Fe 2+ /Fe 3+ ) content was reduced to 4.7% and total iron content was reduced to 8.0% in …
