ZnO和碱土金属氧化物对磷酸盐玻璃结构和性能的影响

The Effect of ZnO and Alkaline Earth Oxides on the Structure and Properties of Phosphate Glasses

为探究掺杂不同二价离子对磷酸盐玻璃性能和结构的影响,本研究以44P_(2)O_(5)-45Na_(2)O-11RO(R=Mg、Ca、Sr、Ba、Zn)组分玻璃为研究对象,探究不同二价离子取代对磷酸盐玻璃的玻璃转变温度(T_(g))、强弱性指数(m)、活化能(E_(a))、硬度(H_(v))、弹性模量(E和G)和泊松比(ν)的调控规律,结果发现:相比于其他碱土元素,Zn的引入会导致磷酸盐玻璃具有较高T_(g)(596K),较低m(34.3),较高H_(v)(279kgf/mm^(2))、E(44.2GPa)和G(17.2GPa)。基于拉曼光谱分析揭示了不同二价离子替换对磷酸盐玻璃性能影响的结构起源。

In order to investigate the impact of doping various divalent ions on the properties and structure of phosphate glasses,this study focused on 44P_(2)O_(5)-45Na_(2)O-11RO(R=Mg,Ca,Sr,Ba,Zn)glasses.The study aimed to explore the effects of different divalent ion doping on the properties and structure of phosphate glasses.The study examined the influence of ion substitution on various properties of the glasses,including glass transition temperature(T_(g)),fragility index(m),activation energy(E_(a)),hardness(H_(v)),elastic modulus(E and G),and Poisson's ratio(ν).The results revealed that,compared to other alkaline earth elements,the introduction of Zn resulted in higher T_(g)(596K),lower m(34.3),higher H_(v)(279kgf/mm^(2)),E(44.2GPa),and G(17.2GPa)for the phosphate glasses.The study also employed Raman spectroscopic analysis to uncover the structural origins of the effects of different divalent ion substitutions on the properties of phosphate glasses.
