Special Issue Information

Dear Colleagues,

The main objective of this Special Issue is to publish outstanding papers presenting comprehensive research in the field of ceramic materials and ceramic composites for modern and functional applications.

The title of the Special Issue covers a wide range of topics in the field of ceramic materials: technology process of ceramic materials, new methods and techniques in ceramic technology process used in order to enhance structure, properties, and application of the ceramic materials, characterization of new multi-omponent ceramic materials, perovskite-type structures, multicomponent solid solutions, PZT-type materials, ferroic and multiferroic materials, lead-free materials, ceramic materials with functional properties, multiferroic ceramic composites, biomaterials, etc.

Comprehensive research includes, among others: modern measure techniques such as X-ray examinations, electron microscopy (SEM, TEM, AFM, STM, etc.), spectroscopy (EDX, XRD, XRF, XPS, etc.), dielectric tests, impedance spectroscopy, electromechanical tests, ferroelectric measurements, electrical conductivity tests, as well as magnetic and magnetoelectric properties, electromagnetic coupling, etc.

It is my pleasure to invite you to submit a manuscript for this Special Issue. Full papers, communications, and reviews are all welcome.

There is a strong need in the industry to develop lead-free piezoelectrics for sensors and actuators. Although these materials have become an important component of many electronic devices, it is very important for the industry to decarbonise ceramic technology, especially through the introduction of modern sintering technologies. Among the many piezoelectric compounds available, Calcium Barium Titanate (BCT) have been widely investigated because of its similar performance to lead-containing Lead Titanate Zirconate (PZT). In this paper, a modified Pechini method for obtaining ceramic Ba0.9Ca0.1TiO3 nano-powders is described. Deviation from the established procedure resulted in the precipitation of the solution or obtaining of a low-quality (poorly crystallized) product with numerous impurities. The samples of BCT materials were examined to find their ideal microstructures and structures; these factors were confirmed by their outstanding X-ray diffraction spectra and high piezoelectric constant values that are comparable to commercial lead-containing materials.

Mechanochemical synthesis offers unique possibility of perovskite phase formation at ambient conditions that is very attractive (simplifies production, allows strict stoichiometry control and brings economic benefits). In this work the mechanochemical synthesis has been used for preparation ofBa1−xCaxTiO3 (0.2 ≤ x ≤ 0.3) powders from simple oxides. The 20 h milled powders have been uniaxially pressed and sintered in order to get the ceramic samples. The sample morphologies have been observed by scanning electron microscopy. Dielectric and impedance studies have been performed on ceramics. The obtained results indicate that the two mechanism of doping occurred. The first one is observed for the lower calcium concentration (below 0.3) and consists of the introduction of calcium ion into the A site of the perovskite structure. The second one is observed for the higher calcium concentration (equal 0.3). In this case the calcium ions partially occupies the B site in the perovskite structure. Both cases have different influence on the final properties of the ceramics because they induce different defects. Full article
