In this study, sintered glass-ceramics made up of jarosite (a hazardous industrial waste) have been obtained by sinter-ing high-iron-content glasses. Thermal gravimetry and differential thermal analysis, carried out in different atmospheres , have been utilized to explain the phase formations in the volume and iron oxidation on the surface of the glass(More)
The sintering and the crystallization of two iron-rich glass compositions (45–75-␮m powder fractions) were studied in air and nitrogen atmospheres. The phase formation was evaluated by differential thermal analysis, while the densification, by dilatometry; the crystalline phases were identified by X-ray diffraction and the structure observed by scanning(More)
Iron-rich glass-ceramics were obtained by the sintering of two glass powders, labeled G1 and G2, at heating rates of 5° and 20°C/min followed by an isothermal step in the 850°–1050°C temperature interval. The sintering process was evaluated by the linear shrinkage; the closed porosity was estimated by density measurements; the structure and the morphology(More)
A glass ceramic composite was obtained by sinter-crystallisation of vitrified municipal solid waste bottom ashes with the addition of various percentages of alumina waste. The sintering was investigated by differential dilatometry and the crystallisation of the glass particles by differential thermal analysis. The crystalline phases produced by the thermal(More)
