Abstract:
In order to manufacture high-value added materials from steel slag, a steel slag-based ceramic was prepared in the paper. X-ray diffraction (XRD) and scanning electron microscopy (SEM) techniques were carried out to characterize the phase formation and the microstructure of the steel slag-based ceramics. Besides, the line shrinkage, flexural strength and water absorption were also determined.Results show that the variation of the line shrinkage and the flexural strength had a positive correlation with the increase of the temperature at the interval 1160°C~1210°C, which was opposite to the change of the water absorption. 1210°C was proved to be the optimum sintering temperature in this work, at which the maximum flexural strength was obtained with a value of 99.39MPa. With the temperature increasing, the quartz phase gradually decreased, participating in the sintering reaction, and the diopside become dominant phase with columnar crystals in 2-5μm at length, which would contribute to the fine performance of the ceramics.
