Article Preview

Glass in Na2O-CaO-SiO2 was synthesized by conventional molten cooling method and then converted to glass-ceramics. Transparent glass-ceramics obtained by controlled crystallization process. DSC, SEM and XRD were used to determine the character temperature, microstructure and crystal type of the glass-ceramics, respectively. The results show the transition temperature of the matrix glass is 620°C and crystallization peak temperature is 730°C. Only Na2Ca2Si3O9 crystal phase was found in the glass-ceramics when the matrix glass was treated at 750°C for 1h. The crystal with size of 0.5um arranged regularly and formed a honeycomb-like structure in the glass-ceramics. UV-visible spectrum test indicate the transmittance of the glass-ceramic is as high as 75% in the visible region.
