Wetting of Na on B”-Al₂O₃/YSZ composites was investigated using the sessile drop technique. The effects of moisture and surface preparation were studied at low temperatures. Electrical conductivity of Na/B”-Al₂O₃-YSZ/Na cells was also investigated at low temperatures and correlated to the wetting behavior. The use of planar B”-Al₂O₃ substrates at low temperature with low cost polymeric seals is realized due to improved wetting at low temperature and conductivity values consistent with the literature.
