【摘要】 研究了TeO₂-Nb₂O₅-P₂O₅三元系统的玻璃形成能力和相关理化性能。结果表明,在TeO₂（80%-90%）,Nb₂O₅（0-20%）,P₂O₅（0-20%）（摩尔分数）成分范围内可以形成性能良好的透明玻璃,碲氧、磷氧和少量的铌氧结构单元共同构建了稳定的链状玻璃网络骨架。TeO₂-Nb₂O₅-P₂O₅玻璃的转变温度为394-425℃、折射率为1.65-1.88。更多还原

【Abstract】 The glass forming ability and the properties of TeO₂-Nb₂O₅- P₂O₅ ternary system were investigated in this paper.It was found that the transparent glasses with good quality can be prepared in the range of TeO₂ 80%-90%,Nb₂O₅ 0-20%,P₂O₅ 0-20%（molar fraction）.The chain-like glass network was stabilized by constructing with tellurium-oxide,phosphorus-oxide and few niobium-oxide coordination polyhedra.The transition temperature of the TeO₂-Nb₂O₅-P₂O₅ glasses is from 394 to 425℃,and its refractive index is from 1.65 to 1.88.更多还原
