Abstract

The objective of our investigations consists in the thermal characterization of SiO2-PbO-Na2O vitreous materials in order to establish their properties for applications mainly as sealants. In order to evaluate the vitreous material − metal adherence, the thermal expansion coefficients (α) from experimental and theoretic data were determined. The differential thermal analysis of studied materials give the information about temperatures characteristic to glass transition, crystallization and melting. Dilatometer measurements were performed in air atmosphere in order to establish thermal coefficients of the materials. Softening and flowing characteristic of the vitreous materials were established by heating microscope measurements. The difference between thermal expansion coefficient (α) of the vitreous materials (10.2 × 10−6K−1 and 17.6 × 10−6K−1) and thermal expansion coefficient of the steel substrate OL 38 (10.8 × 10−6K−1) is under 37%. This value is fit for a good adherence between materials.

密封胶用硅酸铅玻璃材料的热性能

我们研究的目的包括SiO2-PbO-Na2O玻璃材料的热特性，以确定其主要用作密封剂的性能。为了评价玻璃材料-金属的粘附性，从实验和理论数据中确定了热膨胀系数(α)。所研究材料的差热分析提供了玻璃化转变、结晶和熔化的温度特征信息。为了确定材料的热系数，在空气气氛中进行了膨胀仪测量。通过加热显微镜测量，确定了玻璃材料的软化和流动特性。玻璃材料的热膨胀系数(α) (10.2 × 10−6K−1和17.6 × 10−6K−1)与钢基体ol38的热膨胀系数(10.8 × 10−6K−1)的差异小于37%。此值适用于材料之间良好的粘附性。
