The sintering and phase formation of glass press-powders, obtained after melting and re-melting of MSW bottom ash, were investigated by non-isothermal dilatometry and differential thermal analysis. Additionally, a series of composite materials, containing 20 vol \% corundum powders with different fraction size, were prepared and studied. The crystalline phases, formed at different temperatures, were evaluated by X-ray diffraction and the structure of glasses and final materials were observed by scanning electron m...

Alkaline basaltic tuffs, BT, from southern Turkey were characterized and used to obtain cheap sintered glass-ceramic and ceramic materials. The chemical and mineralogical compositions were analyzed by fluourescene spectrometry and X-ray diffraction analyses, respectively. The phase formations were studied by DTA, while the sintering behavior – by differentional dilatometer. The structure of the sintered samples was evaluated by pycnometric techniques and observed by SEM. Due to its high porosity and low crystall...
