Microstructure and Dielectric Properties of Nanostructured TiO2 Ceramics Processed by Tape Castings
Abstract
Effects of different solvent systems and dispersant on tape casting slurries of Ti02 nanopowders (-40nm) were studied by rheological measurements. It was found that XyleneiEthanol with phosphate ester (PE) as dispersant gave the best dispersion quality which resulted in highly homogenous, dense. smooth and crack-free tapes. The presence of phosphate ester inhibited the sintering of Ti02 powders and refined the grain size. Sintered tapes with 200-300nm grain size and relative density over go%, had dielectric constant-100, dielectric loss less than 1% and dielectric breakdown strength (BDS) over 1000KV/cm.
