“…The preparation of precursor powders and ceramic samples of BaSn 1-x Sb x O 3 (x = 0.00 and 0.08), the conditions of XRD analysis and the method for determination of the average grain size were described in our previous paper [25]. Using the value of the unit cell parameter for the BSSO0 sample calculated by PowderCell and LSUCRI software, the structural model of cubic BaSnO 3 was constructed using CrystalMaker software.…”

“…In our previous work we reported on the influence of Sb-doping on properties of spark plasma sintered BSO [25]. Among all presented ceramic samples, the one with composition BaSn 0.92 Sb 0.08 O 3 stood out, having linear I-U characteristic and stable electrical conductivity in the temperature range of 25 °C-150 °C.…”

The influence of structural defects in spark plasma sintered BaSn1-xSbxO3 (BSSO, x = 0.00 and 0.08) ceramic samples on their electrical properties was investigated in the temperature range of 300 – 4 K. X-ray photoelectron spectroscopy (XPS) revealed the presence of point defects, primarily oxygen vacancies (VO) and mixed oxidation states of tin (Sn2+/Sn4+) in both samples. As a result, the undoped BSSO sample exibited a non-standard semiconductor behavior, retaining its temperature-dependent resistivity. The electrical resistivity of the doped samples was three orders of magnitude lower than that of the undoped sample. The presence of structural defects such as VO, mixed oxidation states of the constituent elements, and significant amounts of O- species make the electrical resistivity of the doped sample constant in the temperature range of 300 – 70 K, indicating heavily-doped semiconductor behavior.

Intergranular and intragranular cracks that usually form during sintering of yttrium manganite (YMnO3) ceramic samples hinder the densification process of this ceramic and deteriorate its magnetic and ferroelectric properties. To overcome this problem, mechanochemically synthesized YMnO3 powder was sintered using two different processes: Conventional Sintering (CS) and Pulsed Electric Current Sintering (PECS). All samples were characterized by XRD, SEM and FESEM and their magnetic and ferroelectric properties were investigated. Apart from their phase composition, conventionally sintered ceramic samples showed cracks throughout their whole volume, reaching a maximum relative density of 85 %. However, it was found that PECS process could significantly reduce the presence of cracks within samples whose relative density reached 99.8 %.
