摘　　要：应用扫描电镜、红外光谱等方法研究了钠硼硅玻璃分相过程中玻璃结构的变化。结果表明分相过程中,非桥氧含量增加,同时四配位硼含量降低。由于硅一般以四配位存在,所以当四配位硼含量降低时,硅氧网络和硼氧网络结构差异越来越大,最终导致分相。By using SEM and IR, the structure change in the process of phase separation was studied. Experimental results show that in the process of phase separation, non-bridging oxygens content increase, and meanwhile four-coordinated borons contents decrease. So the differences between Si network and B network become more and more obvious, at last the phase separation is induced.
