Microstructure design and multifunctionality of barium zirconate titanate-barium calcium titanate thin films prepared by chemical solution deposition
Barium zirconate titanate-barium calcium titanate 0.5Ba(Zr0.2Ti0.8)O3-0.5(Ba0.7Ca0.3)TiO3 (BZT-BCT) ceramic exhibits a high piezoelectric response in the vicinity of room temperature. It is an environment-friendly alternative to Pb(Zr1-xTix)O3 (PZT), the most used ceramic material in piezoelectric applications. Thin films meet the requirements related to the miniaturization of electronic components such as in …
Sintering and phase transition behaviour of sodium niobate
Sodium niobate (NaNbO3) is the end member of several alkaline niobate-based solid solutions, which represent an important group of environment-friendly lead-free piezoceramics. Even though alkaline niobates are of considerable technological importance, problems in obtaining high densities and a fine-grained microstructure are still reported and not much is known about the …
Low-temperature sintering of piezoelectric K0.5Na0.5NbO3 ceramics
The KNN solid solution was prepared from pre-synthesized binary compounds of, sodium and potassium niobate in a 1/1 molar ratio. The KNG sintering aid was prepared by homogenizing the pre-reacted binary mixtures of alkaline reagents and germanium oxide with the Na/Ge = 1/1 and K/Ge = 1/1 molar ratios. The …
Solution synthesis of nanoparticles in multicomponent oxide systems
The study of PbZrO3 (PZ), PbTiO3 (PT) and La2Zr2O7 (LZ) prepared by alkoxide sol-gel synthesis is described. PZ and PT sols were prepared from lead acetate, zirconium and titanium n-butoxide, in n-butanol and hydrolysed with Rw (molar ratio of water per lead acetate) between 2 and 15 in neutral medium …
