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