(Springer, 2021-07)
The development of piezoelectric ceramics with high energy conversion efficiency is of decisive importance for the requirements of the advanced energy harvesting devices toward miniaturization and integration. Lead ...
Mechanical Properties Enhancement in Potassium-Sodium Niobate Lead-free Piezoceramics: The impact of chemical modifications
(Springer, 2016-12-15)
The development of (K0.44Na0.52Li0.04)(Nb0.86Ta0.10Sb0.04)O3-based (KNL-NTS) ceramics is attracting great interest because of environmental concerns. Most of the efforts have been concentrated on improving the electrical ...
Processamento e propriedades do sistema ferroelétrico (Li,K,Na)(Nb,Ta)O3 dopado com CuO
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Física - PPGF, 2015-03-09)
The search for new lead-free piezoelectric materials has been a major goal of many scientists in recent years. The main cause is the replacement of widely used lead zirconate titanate (PZT) based ceramics due to the highly ...
Influences of secondary phases on ferroelectric properties of Bi(Na,K)TiO3 ceramics
(Elsevier, 2014-12-24)
The effect of secondary phases on ferroelectric properties of Bi0.5(Na0.8K0.2)0.5TiO3 (BNKT) is studied. Ceramic powders are prepared by the solid-state reaction method where the influence of different sintering temperatures ...
