TiO2 nanotubes film/FTO glass interface: Thermal treatment effects
(ETRAN, 2022)
Pure Ti films deposited by radio-frequency magnetron sputtering on FTO glass were anodized to fabricate TiO2 nanotubes (NTs) arrays. The TiO2 NTs/FTO samples were sintered at 450, 550 and 630°C, in ambient air. The thermal ...
Microstructural and Optical Properties of MgAl2O4 Spinel: Effects of Mechanical Activation, Y2O3 and Graphene Additions
(Basel : MDPI AG, 2021)
Magnesium aluminate and other alumina-based spinels attract attention due to their high hardness, high mechanical strength, and low dielectric constant. MgAl2O4 was produced by a solid-state reaction between MgO and α-Al2O3 ...
A new neural network approach to density calculation on ceramic materials
(World Scientific Pub Co Pte Ltd, 2021)
The materials’ consolidation, especially ceramics, is very important in advanced research development and industrial technologies. Science of sintering with all incoming novelties is the base of all these processes. A very ...
Niobium doping effect on BaTiO3 structure and dielectric properties
(Elsevier, 2020)
The effect of Nb on the microstructure and dielectric properties of BaTiO3 ceramics was investigated. The Nb/Mn–BaTiO3 ceramics were prepared using a conventional solid-state method. The concentration of Nb varied from 0.1 ...
Multiferroic Heterostructure BaTiO3/ε-Fe2O3 Composite Obtained by in situ Reaction
(Belgrade : International Institute for the Science of Sintering, 2021)
Solid-state reaction between BaTiO3 and Fe2O3 was used to produce a multiferroic heterostructure composite. Commercial BaTiO3 and Fe(NO3)3•9H2O were suspended in ethanol for 30 minutes in an ultrasound bath. The prepared ...
Multi-phase (Zr,Ti,Cr)B2solid solutions: Preparation, multi-scale microstructure, and local properties
(Tsinghua University Press, 2023)
Multi-phase ceramics based on ZrB2, TiB2 and doped with CrB2 and SiC were prepared by powder metallurgy and hot pressing to explore the possibility of obtaining multi-scale microstructures by super-saturation of complex ...
Electronic properties of BZT nano-ceramic grades at low frequency region
(Belgrade : ETRAN, 2023)
BZT ceramics was prepared by using fine powder mixture of BaCO3, TiO2 and ZrO2 in the respective molar ratio to form Ba(Zr0.10Ti0.90)O3 via solid state reaction at elevated temperature. The prepared BZT was milled in the ...
Final‐stage densification kinetics of direct current–sintered ZrB2
(Wiley, 2023)
Final-stage sintering was analyzed for nominally phase pure zirconium diboride synthesized by borothermal reduction of high-purity ZrO2. Analysis was conducted on ZrB2 ceramics with relative densities greater than 90% using ...
