| Glass-ceramics were produced by sintering method from industrial waste materials such as fly ash, blast furnace slag and boron waste. The sintering behavior and machinability of glass-ceramic compositions were investigated. Additives were added to waste materials for enhancement of machinability and sintering properties. All starting materials were mixed by ball milling for 2 h using alumina media. The mixed and milled powders were sieved to grain sizes smaller than 75 μm and pressed at 100 MPa. The pressed samples were sintered at 900°C, 1000°C and 1100°C for 1 h in an electric furnace using a heating rate of 5°C/min. Some characterization tests such as X-ray diffraction (XRD), scanning electron microscopy (SEM) and machinability tests were performed on sintered samples. The results indicated that all samples exhibit good sintering and machinability properties. |
