在硅钼电阻炉中，在氮气气氛下，在1600℃下熔融2小时，制备了M-Si-Al-O-N(M=Y，Ca，Mg)氧氮化物玻璃。根据差示扫描量热仪(DSC)测量提供的信息选择合适的热处理温度。利用X射线衍射仪和扫描电子显微镜研究了添加不同改性剂的微晶玻璃的析晶行为。结果表明，对于该系统，热处理对微晶玻璃的晶相体积分数和显微结构有影响，而对析出的晶相种类影响不大。
M–Si–Al–O–N (M=Y, Ca, Mg) oxynitride glasses were prepared by melting batches at 1600 °C for 2 h under N2atmosphere in a Si–Mo-heated resistance furnace. The appropriate heat treatment temperatures were selected according to the information provided by the differential scanning calorimeter (DSC) measurement. X-ray diffraction (XRD) and scanning electron microscope (SEM) were used to study the crystallization behavior of the glass–ceramics with different modifier elements. The results indicate that for this glass system, heat treatment has an effect on volume fraction of the crystalline phases and the microstructure of the glass–ceramics, whereas the effect on the types of the crystalline phases precipitated is small.
