中温固体氧化物燃料电池封接玻璃的结构与封接性能：TiO2含量对TiO2-CaO-SrO-B2O3-SiO2玻璃体系的影响
Structures and Sealing Properties of TiO2-CaO-SrO-B2O3-SiO2 Glasses for Intermediate Temperature Solid Oxide Fuel Cells: Effect of TiO2 content
本文中，TiO2作为CaO-SrO-B2O3-SiO2玻璃体系的形核添加剂，通过改变体系的结晶过程来调整微晶玻璃体系的性能。结果表明，添加TiO2可以加速玻璃体系的结晶过程。生成的Sr(TiO3)有以下作用：经过750 oC,100h的热处理后，微晶玻璃的CTE从10.9×10-6 /K降到9.8×10-6 /K；提高体系在800 oC的电子导电性（7.9×10-8 S/cm 升到6.9×10-5 S/cm）；提高封接玻璃的化学稳定性。同时，发现当玻璃体系中含有4 mol%和8mol%的TiO2时，玻璃体系与含Cr的连接体（本文使用430 SS不锈钢）之间具有良好的密封效果。
In this paper, TiO2 is added as the nucleation agent to CaO-SrO-B2O3-SiO2 sealing system to tailor the properties of glass-ceramic seals by changing the crystallization process. The coefficient of thermal expansion (CTE) of quenched glasses and glass-ceramics (heat-treated at 750oC for 100 hours) does not change significantly with the addition of TiO2. The formation of Sr(TiO3), with the addition of TiO2, leads to the improved chemical compatibility of sealing glasses as well as the increase in electrical conductivity (e.g., from 7.9×10-8 S/cm to 6.9×10-5 S/cm at 800oC). In addition, the good bondage are observed at the interface between Cr-containing interconnect (430 SS) and glass containing 4-8 mole% TiO2.
