放射性滑膜切除用镝锂硼玻璃的性能及红外光谱结构研究

Structural study by IR spectra and properties investigation of dysprosium lithium borate glasses intended for in vivo radiation synovectomy

测定了镝锂硼玻璃(DyLB)的密度和硬度,用红外吸收光谱测定了DyLB玻璃的结构,从组成-结构-性质的关系上分析了Dy2O3对DyLB系统玻璃结构及性能的影响。结果表明Dy2O3使DyLB玻璃中的[BO3]转变为[BO4],同时Dy3+具有积聚效应,使DyLB玻璃网络被强化,玻璃的密度、硬度均升高。

Structure/property relationships for the Dy2O3-Li2O-B2O3 glasses studied, by measuring their densites and hardness, as well as using infra-red spectra （IR）. Preliminary results show that,increasing Dy2O3 inforce the structure of DyLB glass by transforming [BO3] into [BO4] in the glass, meanwhile, the aggregational action of Dy^3＋ ion also inforce the net-work of DyLB glasses, thus, glass density and hardness both increased.
