AbstractIn this contribution, we studied the influence of coarsening SDC powder on interaction with YSZ powder with the purpose to alleviate the interaction between selected electrolyte materials during the cell co-firing process. The main findings are that the heat treatment of SDC increases the temperature at which a new solid solution phase combining SDC and YSZ completely forms, that the bulk conductivity of SDC+YSZ pellets is positively impacted by the coarsening of SDC through heat treatment, and that the dense pellet of the new solid solution formed by the sintering of SDC+YSZ at 1500°C in air is not stable under a reducing atmosphere. Coarsening of SDC powder also led to a higher sintering temperature of the SDC+YSZ powder mixture. ©The Electrochemical Society.
