Synthesis of polycrystalline BaZrO3 coatings

Barium zirconate was prepared by liquid phase sintering at low temperatures and used as a substrate for a YBCO melt process. The liquid phase was provided by barium cuprate melt, barium peroxide melt or barium zirconate liquid (in case of plasma spraying). The infiltration resistance against the barium cuprate melt could be improved, but is not yet sufficient for application.
