“…Those tested in ceramic batches are usually poor in iron but may be rich in manganese (Table 7). BFS were experimented under different strategies: in porcelain stoneware (12-30%) as a substitute of feldspar even mixed with BOFS Zhao et al, 2015;Pal et al, 2016) or iron ore tailings and/or coal fly ash .…”

“…The mass loss continues as the temperature is raised; indeed, DTG analysis shows three small peaks at 1099, 1047 and 1107℃ for 0, 5 and 15 wt.% SLGW, respectively. This is related to mullite formation by crystallization [7]. The total mass loss values in the mixtures 0, 5, and 15 wt.…”

“…We can notice, also, slight increase in the flexural strength of samples C2, C3 and C4, where we have SLGW incorporation. This increase can be explained by the difference in thermal expansion coefficient between glass matrix, mullite, quartz and grains of anorthite formed; as they contribute to a higher prestressing during the cooling process [7,35]. In the C4 samples, the flexural strength decreased compared to C3; which can be attributed to the presence of a high amount of low-density liquid phase that leads to a bulging of the ceramic samples.…”

In this study, the effect of substitution of feldspar by soda-lime glass waste (SLGW), on rheological behavior, thermal, physical-mechanical and structural properties of sanitary-ware vitreous china (VC) bodies, has been evaluated. The findings show a positive effect on the rheological behavior of the slip, to viscosity, thixotropy, density and casting process. Indeed, during the firing stage at 1230°C, the use of 20 wt. % of SLGW in the composition of VC bodies, improved Bulk density (2 to 2.52 g/cm3), reduced water absorption (0.35 to 0.02%), and increased flexural strength (33 to 51 MPa). The fired samples were characterized using X-ray diffraction, SEM and FTIR analysis; results indicate that Mullite and Quartz are the major phases, with a little presence of anorthite phase formed by SLGW additions. From TGA/DTG analysis, it was found that the use of SLGW (15 wt. %) reduces mass loss of VC bodies (8.83 to 8.53%). These positive results open new horizons for using this waste, as a sound environmental, technological and economic solution.

“…Therefore, steel slag can be used to develop ceramic materials. Previous researchers have done a great deal of work on the preparation of steel slag as a raw material in ceramics [10][11][12][13][14]. Zhang et al [15] prepared steel slag ceramics by mixing steel slag, clay, quartz, feldspar, and talc.…”

In this paper, stoneware was prepared using steel slag shale as the main raw material. A typical ceramic sintering procedure was used to evaluate the effects of a sintering temperature of 1050~1130 °C on the linear shrinkage, water absorption, bulk density, and flexural strength parameters of stoneware samples. The stoneware samples were characterized by XRF, XRD, and SEM. The results showed that the performance of the steel slag content of 40% at sintering temperature of 1110°C was better than the other samples. The main phases of the sample are composed of the quartz phase, the pyroxene phase, and the anorthite phase. Among them, the water absorption rate is 1.36%, the linear shrinkage rate is 11.36%, the bulk density is 2.46 g/cm3, and the flexural strength is 71.13 Mpa. Anorthite and pyroxene improve the bending strength of stoneware samples, which is realized by the prestress mechanism.
