(1) This was accompanied by a strength decrement and it is concluded that these yttria-stabilized ZTA and TZP materials are unsuitable as implant materials.
(2) Composites containing ceria and magnesia as substitutes for yttria behave similarly.
(3) Thin films of the superconductive oxide YBa2Cu3O7-x have been made by electron-beam coevaporation of the metals in an oxygen atmosphere onto single-crystal [001]-oriented SrTiO3 and yttria-stabilized zirconia (YSZ) substrates.
