Fabrication of Translucent ZrO ₂ Film by a Modified Doctor Blade Method

Dense, translucent ZrO ₂ (stabilized by Y ₂ O ₃ ) films were made by a modified doctor blade method. Loosely coagulated ceramic powders left after decomposition of methylcellulose film were pressed onto polystyrene films to densify the powder compact. The films were heated at 1700°C in air. The thickness of the films was ∼100 μm. Very few grain boundaries appeared along the direction perpendicular to the film surface.
