【摘要】 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。更多还原

【Abstract】 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 into in the glass,meanwhile,the aggregational action of Dy3+ ion also inforce the net-work of DyLB glasses,thus,glass density and hardness both increased.更多还原
