Abstract
"A drop-on-demand inkjet system was assembled that allowed viewing of droplet formation and flight. A dilute CeO2 ink was made and printed onto LSM substrates. Continuous line patterns with ~200 µm line widths and 1-2 µm thick sintered films were made. Inks containing 0.5-100 mol% Nb2O5 were made and lines printed with them were laminated between layers of tape cast BaTiO3. Regions of inhibited grain growth caused by diffusion of the Nb during densification were observed. Using the observed diffusion geometries and data on resistivity and dielectric permittivity of Nb-doped BaTiO3, software models were made of diffusion gradients placed at the end of electrodes in multilayer ceramic capacitors. Maximum electric fields were calculated versus frequency and layer thickness to evaluate the effect of the diffusion gradients on capacitor breakdown strength. For direct current applications, possible layer thickness reductions of 60-80% or more were predicted by surrounding the electrode edge with a 20 µm wide region of diffused Nb. For alternating currents over 1000 Hz, a possible layer thickness reduction of 35% was predicted for a 120 µm wide diffuse region"--Abstract, page iii.
