Processing and Dielectric Properties of TiO₂ Thick Films for High-energy Density Capacitor Applications
International Journal of Applied Ceramic Technology
Abstract
Nanosized titanium dioxide (TiO2) powders (∼40 nm) were used for preparation of tape-casting slurries. Effect of various solvents and dispersants on the dispersability of TiO2 slurries was studied by sedimentation tests and rheology measurements. TiO2 green tapes were prepared by tape-casting method and densified at 1000°C with a sintered density >95%. Dielectric properties of TiO2 tapes were studied by measuring of dielectric constant, loss factor and dielectric breakdown strength (BDS) with respect to their microstructural development. BDS values as high as ∼1400 kV/cm were obtained for sintered tapes so that energy densities up to 14 J/cm3 could be achieved.
