摘要
本文用Raman光谱研究了钠硼硅基础玻璃的结构及高价氧化物P_2O_5和M_0O_3对其结构的影响。结果表明,钠硼硅玻璃结构符合“基因模型”理论,M_0O_3以其阳离子的高场强作用使结构中三配位硼增加,而P_2O_5受配位关系制约使结构中四配位硼增加。
The structure of sodium borosilicate base glass and the effects of P2O5 and M0O3 were studied in this paper by means of Raman spectrum. The results showed that the structure of base glass is in accord with the theory of the Group Models. M0O3 induces the number of BO3 triangles to increase for its high cationic field strenghth, otherwise P2O5 increases that of BO4 tetraheara because of the limit of its coordination.
