Cr+6 Controlled Nucleation in SiO2-MgO-Al2O3-K2O-B2O3-F Glass Sealant (SOFC)

Cr+6 Controlled Nucleation in SiO2-MgO-Al2O3-K2O-B2O3-F Glass Sealant (SOFC)

This study highlights the strong effect of chromium (Cr6+) as a nucleating agent for SiO2-MgO-Al2O3-B2O3-K2O-F glass sealant. In the process, Al2O3 from the base glass was gradually substituted by K2Cr2O7, which considerably tuned the crystallization characteristics, microstructure, thermal, and mec...
