摘要/Abstract

摘要： ZnO-B2O3-SiO2玻璃是一类重要的低熔点玻璃,在玻璃深加工领域具有重要的应用.在ZnO-B2O3-SiO2玻璃中,ZnO含量的变化对玻璃结构和性能产生显著的影响.因此,本文调整ZnO-B2O3-SiO2玻璃中ZnO的引入量,结合DSC、红外光谱等测试手段,研究ZnO对玻璃的网络结构、热学性能、化学稳定性的影响规律.研究结果表明:随着ZnO含量的增多,Zn2+以[ZnO4]四面体结构进入到玻璃网络体结构,出现了[BO4]结构体向[BO3]结构体的转变.ZnO含量的增加,降低了玻璃的Tg和Ts,增大热膨胀系数,增强化学稳定性.ZnO的最佳引入量是32%,此时玻璃具有较低的Tg(495 ℃)和Ts(529 ℃),热膨胀系数为8.96×10-6 /K ,耐酸碱性能等级均为A级.在ZnO-B2O3-SiO2玻璃涂覆应用中,最佳的烧结温度为560 ℃,在ZnO含量为 32%时,涂覆层硬度最佳,硬度值为648.9 Hv.

Abstract: The ZnO-B2O3-SiO2 glass is an important sort of the low-melting glass which has important applications in deep processing field of glass.In the ZnO-B2O3-SiO2 glass,the ZnO content have a significant influence on the structure and properties of the glass.The influence of ZnO on the structure and properties of ZnO-B2O3-SiO2 low-melting glass was studied by DSC,FTIR,CTE test,chemical stability test and he coating application.It was found out that the increase of ZnO could reduce the characteristic temperature of ZnO-B2O3-SiO2 low-melting glass,and increase the CTE and chemical stability.The results showed that Zn2+ with a form of [ZnO4] entered the network structure of glass,and there was a transition [BO4] tetrahedral structure to [BO3] trihedral structure with the increase of ZnO.The optimum amount of ZnO was 32%.In this situation,ZnO-B2O3-SiO2 low-melting glass had the lowest Tg (495 ℃) and Ts (529 ℃),and the CTE was 8.96×10-6 /K.The chemical stability was A level.In the coating application of low-melting glass,the glass in that ZnO content is 32% present the best hardness which is 648.9 Hv.
