High-density YSZ tapes fabricated via the multi-folding lamination process

A new method of ceramic processing to obtain high green and fully sintered yttria-stabilized zirconia (YSZ) ceramic parts has been studied. The procedure involved slip casting, multi-folding lamination, and sintering. A rheological study revealed correlation between compositional parameters and densities. A particular method of folding and lamination we named multi-folding lamination was proved to be an appropriate route to obtain dense, homogeneous green bodies, reaching density values of ca. 61%. Further studies on the sintered parts were performed in this work, obtaining YSZ sintered tapes suitable for the use in high temperature solid-state devices. This tapes, sintered at 1550 °C, reached values of 98% of theoretical density and average particle sizes within 1.7–12 μm.
