Preparation and properties of Bi6Ti5WO22: a new phase in the Bi2O3–TiO2–WO3 system
In a recent report, the evaluation of the phase relations in the Bi2O3–TiO2–WO3 ternary system has shown the existence of a new phase with nominal composition close to Bi6Ti5WO22. In the present contribution we a...

Thermal evolution of ZnO-Bi2O3-Sb2O3 system in the region of interest for varistors
In facing the design of new processing strategies for ZnO based ceramic varistors, a precise control of its microstructural development during sintering is demanded. Addition of dopants to zinc oxide results i...

Ceramic–electrode interaction in PZT and PNN–PZT multilayer piezoelectric ceramics with AG/PD 70/30 inner electrode
Pb(Zr0.53Ti0.47)O3(PZT) and PbNi1/3Nb2/3O3-PZT (PNN–PZT) multilayers with Ag/Pd 70/30 inner electrodes have been studied from the point of view of the ceramic–electrode interaction. PZT multilayers have shown ...

Phosphor-doped BaTiO3: Microstructure development and dielectric properties
The phosphor cation retards BaTiO3 formation during the first reaction stage, and favours Ba2TiO4 formation. As a consequence, the end of the reaction is only accomplished at 1150 °C. The average particle size of...
