| Summary: | A glass-ceramic material was produced from class F Malaysian coal fly ash by using vitrification method. Determination of physico-chemical properties of formed samples was conducted using X-ray diffraction (XRD), scanning electron microscopy (SEM), Rockwell hardness and toxicity characteristic leaching procedure (TCLP). XRD analysis showed an amorphous annealed material followed by the strong crystal growth of quartz and mullite phases over the heat treatment stage. Growth of crystalline phase was also observed. The TCLP results showed that the glass-ceramic was non-hazardous. Results showed that it was technically possible to use vitrification to produce glass-ceramics from Malaysian coal fly ash. |
