Barium zirconate was prepared by liquid phase sintering at low tempera
tures and used as a substrate for a YBCO melt process. The liquid phas
e was provided by barium cuprate melt, barium peroxide melt or barium
zirconate liquid (in case of plasma spraying). The infiltration resist
ance against the barium cuprate melt could be improved, but is not yet
sufficient for application. (C) 1998 Elsevier Science S.A. All rights
