High strength lightweight glass-ceramics were fabricated by using waste flyash as main raw material. The effects of the utilization rate of the fly ash, nucleation agents, and sintering temperature on the properties of the glass-ceramics were studied. The flyash utilization rate as high as 70% was achieved in realizing an optimal glass-ceramics property at a sintering temperature of 1300 °C. When nucleation agents of Fe2O3 ( Read More
