Effect of lanthanide doping on structural, microstructural and functional properties of K0.5Na0.5NbO3 lead-free piezoceramics
(2016-11-15)
Article
Open AccessLanthanides-doped K0.5Na0.5NbO3(KNN) lead-free piezoelectric ceramics are prepared by conventional solid-state reaction. The effects of lanthanum concentration and the lanthanide type on the structure, microstructure and ... -
Extensive domain wall contribution to strain in a (K,Na)NbO3-based lead-free piezoceramics quantified from high energy X-ray diffraction
(Elsevier, 2016-08)
Article
Open AccessThe origins of high piezoelectric properties in the lead-free (K,Na)NbO3-based tetragonal composition (K0.44Na0.52Li0.04)(Nb0.86Ta0.10Sb0.04)O3 (KNL-NTS) is investigated by quantifying the intrinsic and extrinsic contributions ... -
Extrinsic response enhancement at the polymorphic phase boundary in piezoelectric materials
(2016-04-04)
Article
Open AccessPolymorphic phase boundaries (PPBs) in piezoelectric materials have attracted significant interest in recent years, in particular because of the unique properties that can be found in their vicinity. However, to fully ... -
Understanding the piezoelectric properties in potassium-sodium niobate-based lead-free piezoceramics: interrelationship between intrinsic and extrinsic factors
(Elsevier, 2017-09)
Article
Open AccessLead zirconate titanate (PZT) based ceramics are currently enjoying a wide use in piezoelectric devices despite lead toxicity. Due to growing environmental concerns, the attention on piezoelectric ceramics has been moving ...
