Diffusion behavior of Ag electrodes into (Bi_1/2Na_1/2)TiO₃ ceramics

Complex diffusion behavior of oxygen in nanocrystalline BaTiO3 ceramics.

(18)O/(16)O exchange annealing and subsequent Time-of-Flight Secondary Ion Mass Spectrometry (ToF-SIMS) analysis is used to investigate oxygen transport in dense, nanocrystalline (average grain size d ≈ 300 nm) ceramics of nominally un-doped BaTiO3. Isotope penetration profiles are obtained as a function of temperature, 973 < T/K < 1173, at an oxygen activity aO2 = 0.20 and as a function of oxy...

Compatibility of RuO2 electrodes with PZT ceramics

Because of its high electrical conductivity and good diffusion barrier properties ruthenium dioxide (RuO2) is a good electrode material for use with ferroelectric lead zirconate–titanate (PZT) solid solutions. Under certain conditions, RuO2 can react with PZT to form lead ruthenate (Pb2Ru2O6⋅5) during processing at elevated temperatures resulting in lead depletion from PZT. The standard Gibbs e...

Ag/Biochar Composite for Supercapacitor Electrodes L.Kouchachvili

The development of new electrical energy storage devices and the improving of existing ones e.g. batteries and supercapacitors (SC) has become extremely important due to increased application of these devices in transportation and in renewable energy storage. Among them, SC are more capable of generating higher power density than are batteries, and are gaining particular interest. They are used...
