| Summary: | There are a lot of waste materials consist of silicate based such as coal combustion
ash, slag from steel production, fly ash, mud, as well as glass cullet or mixtures to produce
glass-ceramics. This research work using clam shell (CS) ash and soda-lime-silica (SLS) waste
glass powder for fabricating novel SiO2-Na2O-CaO (SNC) glass-ceramic. The samples were
composed of SLS (50%), Na2CO3 (30%), and CS (20%) in weight percentage via conventional
melt-quenching technique and solid-state sintering technique. The samples were investigated
via X-Ray Diffractometer (XRD), Field emission microscope (FESEM), and microvickers
hardness tester. The samples were sintered at 550-950 °C to investigate the influence of
microstructural effect on microvickers hardness properties at applied force 0.5 and 1.0 kgf. The
optimal Vickers hardness properties at sintering temperature 850 °C due to high crystallization
of SiO2 phase from the residual glass and CaO content enhanced the viscosity flow, high
compactness of particles arrangement and densification of sample. |
