摘要
2MgO-Al2O3-3.3P(2)O(5) glasses with increasing amounts of SiO2 are considered for sealing applications in solid oxide fuel cells (SOFC). The change in chemical durability under SOFC anode conditions and the linear thermal expansion are measured as functions of the SiO2 concentration. Raman spectroscopy analysis of the glasses reveals no sign of important changes in the glass structure upon SiO2 addition. Some increase in glass durability with SiO2 concentration is reported and its cause discussed. (C) 1999 Elsevier Science B.V. All rights reserved.
