Popis: The ZnO-B2O3-SiO2 base glass was prepared with high temperature melting method. The base glass powder was investigated by differential thermal analysis (DTA) and the glass-ceramic was investigated by X-ray diffraction (XRD) analysis and scanning electron microscope (SEM). The results indicated that the structure adjustment of the base glass appeared around 595°C and the exothermic peaks turned up around 740°C and 860°C in the DTA testing. But the strength of the structure adjustment and the exothermic peaks was weak. The XRD results showed that the non-crystal glass was amorphous form without diffraction peaks appearing. The crystallization glass obviously contained crystals, which were more amount of ZnAl2O4 crystal and a small amount of NaAlSiO4 crystal. Through the SEM, the surface morphology of the glass-ceramic showed that the amount of the crystal was dense.
