We specialize in producing Yttria Stabilized Bismuth Oxide (YBO or YSB), bismuth oxide stabilized with 25 mol % yttrium oxide, a material that upon firing forms a dense highly ionically conductive thin film electrolyte layer for use in intermediate temperature solid oxide fuel cell (IT-SOFC) electrochemistry structures. Yttria doped Bismuth Oxide belongs to a class of doped oxide compounds with ionic conductivity exceeding yttria stabilized zirconia (YSZ) electrolytes.
