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...

The present work discusses the synthesize of sintered granite–like glass-ceramics obtained by vitrification of hazardous industrial wastes. The chemical resistance of parent wastes and glasses were classified by the toxic characteristics leaching procedure (TCLP), whereas the crystallization behaviour was evaluated by DTA and XRD. The thermal and mechanical properties of final glass-ceramics were also measured and discussed. The obtained glass-ceramics have attractive appearance, elevate chemical durability and ...

The feasibility to substitute feldspar raw materials in a porcelain stoneware body with waste Cathode Ray Tube (CRT) glass was investigated. Various compositions, containing different percentages of feldspars and CRT glass, were compared. The densification process was studied by non-isothermal dilatometry and the degree of sintering was evaluated by pycnometric techniques. The structure and phase composition of the final ceramics were studied by SEM and XRD, respectively. The technological parameters and the mecha...
