Electric field-assisted pressureless sintering of zirconia–scandia–ceria solid electrolytes Abstract: Electric field-assisted (flash) pressureless sintering experiments were carried out in ZrO2ceramics doped with 10 mol% Sc2O3 and 1 mol% CeO2 (10Sc1CeSZ). All experiments were conducted isothermally at 1050 °C for 2–5 min with […]
Dielectric and non-ohmic properties of Ca2Cu2Ti4-xSnxO12 (0.0 ≤ x ≤4.0) multiphasic ceramic composites Abstract: Multiphasic Sn4+ substituted Ca2Cu2Ti4-xSnxO12 (0.0 ≤ x ≤ 4.0) ceramic composites were prepared by solid-state reaction. Their crystalline structure, microstructure, dielectric […]
EDTA-functionalized Fe3O4 nanoparticles Abstract: This study analyzes the synthesis and characterization of functionalized Fe3O4 nanoparticles by ethylenediaminetetraacetic acid (EDTA). The syntheses were performed using the co-precipitation method under different experimental conditions: nitrogen atmosphere versus ambient atmospheric […]
A versatile approach for the preparation of ceramics with porosity gradient: by using manganese and tin oxides as a model Abstract: Porous ceramics that exhibit porosity gradient are considered promising materials from the industrial point of […]
Blue and red light photoluminescence emission at room temperature from CaTiO3 decorated with α-Ag2WO4 Abstract: CaTiO3 (CT) and α-Ag2WO4 (AW) semiconductors are widely known for their interesting electrical and photoluminescence (PL) properties. In this study, we decorated CT with AW […]
