The diploma thesis is focused on preparation of thin and highly flexible ceramic tapes from zirconia with a thickness from 70 to 200 m. The thesis is divided into two parts. The first part presents a literary research that focuses on the properties of zirconium dioxide, the preparation of thin ceramic foils and the evaluation of the mechanical properties of ceramic materials. The second part is experimental. It deals with the preparation of thin ceramic foils from colloidal ceramic suspensions produced by epoxy gel-tape casting method. The suspensions were prepared from zirconium dioxide stabilized by 2 and 3 mol.% of yttrium oxide. The maximum deflection and strength was determined on sintered foils. The maximum biaxial strength of 1806 MPa was achieved for 3Y-PC 75 foils with a thickness of 190 m. The maximum deflection of 10.5 mm at a ceramic foil thickness of 75 m was achieved in a 3-point bend with a support span of 30 mm on 3Y-PC 75 samples. At a support distance of 50 mm, the samples were pushed through the gap without damage. These results indicate excellent mechanical properties of the prepared ceramic foils.
