Özet

A thermal power plant fly ash was used to produce aceramic material by sintering technique. Coal fly ashsamples were sintered at the temperature range of 1273-1348 K for 2 hours to investigate the effect of firingtemperature on microstructure and physical propertiesof the produced materials. X-ray diffraction (XRD)analysis revealed that quartz (SiO2), mullite (Al6Si2O13),anorthite (CaAl2Si2O8) and enstatite ((Mg,Fe)SiO3)phases detected in the fly ash sample disappeared;wollastonite (CaSiO3) and gehlenite (Ca2Al2SiO7)phases occurred in the ceramic samples. Scanningelectron microscopy (SEM) investigations wereconducted on the produced ceramic materials toinvestigate the microstructural evolution of the samples.The dentritic dense crystalline structure was observed inthe produced samples. Density and hardness values ofthe produced samples increased significantly withincreasing sintering temperature while water adsorptionand porosity values decreased. The overall resultsshowed that it is possible to produce ceramic materialsfrom the coal fly ash with high density, low porosityand water adsorption values.
