Abstract：Glass-ceramic was prepared from raw materials mainly containing boron mud, and the crystallizability of glass ceramic of CaO-MgO-Al2O3-SiO2 system was studied by means of DTA, XRD and SEM. Effects of sintering time and crystallizing time on the microstructure of glass ceramic were also analyzed. The results show that the main crystalline phase of the glass ceramic is hedenbergite, while the subordinate crystalline phases are spinel and olivine, its grain sizes are about 2~5 μm, with dendrite, columnar crystal and bulk crystal existing in aggregation, and the optimum sintering time and crystallizing time are 4 and 4 h, respectively.
