Thermochemical compatibility of a seal glass with different solid oxide cell components

Academic Article

Abstract

  • Thermochemical compatibility of an aluminosilicate glass (SABS-0) with Crofer 22 APU, nickel, and NiTiHf alloy has been studied for solid oxide cell use. Local SABS-0 devitrification occurs near the interfaces of Crofer 22 APU/SABS-0 and Ni/SABS-0 samples. But extensive SABS-0 devitrification is observed at the NiTiHf/SABS-0 interface. The SABS-0 elements diffuse a few microns into the Crofer 22 APU alloy and the nickel, or vice versa. But the SABS-0 and NiTiHf elements diffuse into each other at ∼25 μm. The SABS-0 glass is thermochemically compatible with the Crofer 22 APU and the nickel but not with the NiTiHf alloy. © 2009 The American Ceramic Society.
