氧化物添加对Bi_2O_3–B_2O_3–ZnO低熔点玻璃结构与性能的影响
Effect of Oxides Additive on Properties and Structure of Low-Melting Sealing Bi2O3-B2O3-ZnO Glasses
摘要
Abstract
Glass samples with Bi2O3–B2O3–ZnO as a matrix and different oxides(i.e.,SiO2,GeO2,TeO2and Sb2O5) were prepared by a conventional melt quenching method.The effect of oxides additive on the structure,transformation temperature,softening temperature,crystallization peak temperature,thermal expansion coefficient,bending strength and chemical durability of the samples were analyzed.The structure of the glasses was characterized by Fourier transform infrared spectroscopy(FTIR),X-ray diffraction(XRD) and differential scanning calorimetry(DSC).The results indicate that the most effective way to decrease the thermal expansion coefficient is the addition of SiO2,and the glass transformation temperature and softening temperature are lowest when TeO2is added.The addition of Sb2O5could reduce the glass transformation temperature and softening temperature,resulting in the maximum ΔT and the improvement of devitrification resist ability.Also,the glass sample with Sb2O5additive has a lower thermal expansion coefficient,the greatest bending strength and the best chemical durability.The structure change of the glasses was also studied by using FTIR,XRD and DSC.关键词
