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 …
Investigations and separation of various contributions to dielectric response of advanced ceramic and polymeric materials
Dielectric materials, used to control and store charges and electric energy, play a key role in modern electronics and electric power systems. Dielectric spectroscopy is a versatile method, well-suited for detection, separation and characterization of various contributions to dielectric response of advanced ceramic and polymeric materials, as it enables understanding …
Processing-Dependent Broadband Dielectric Properties of KTaO3 Ceramics, Films and KTa0.6Nb0.4O3 Films
KTaO3 belongs to the group of incipient ferroelectrics, which are materials important from the fundamental, as well as from the applications, point of view. It is well known in its single-crystal form; however, the processing of technologically interesting ceramics and thin films is a challenging task and knowledge of their …
