Novel cordierite-acicular mullite composite for diesel particulate filters
(Ceramics International, 2021)
Cordierite-acicular mullite composites containing 0, 25, 50, 75 and 100 wt% of mullite were fabricated from waste MoSi2 and commercial powders of Al2O3 and spinel (MgAl2O4). Careful oxidation of pulverised waste MoSi2 ...
Structural and morphological characterization of iron-doped sol-gel derived mullite powders
(Ceramics International, 2020)
The structural and morphological properties of iron-doped mullite powders are the subject of the present study. The powders of undoped and iron-doped mullite in the composition range of 3–15 wt% Fe2O3 were synthesized by ...
MgAl2O4:Cr3+ luminescence thermometry probe in the physiological temperatures range
(Ceramics International, 2021)
Temperature sensing from the photoluminescence of MgAl2O4:Cr3+ ceramic powder is systematically investigated. Material was prepared by self-propagating high temperature synthesis method. In this host, Cr3+ experiences the ...
Electrochemical and structural study on cycling performance of γ-LiV2O5 cathode
(Ceramics International, 2021)
Electrochemical and structural properties of LiV2O5 cathode were investigated. Obtained by solid state reaction at high temperature the material crystallized as gamma polymorph phase, γ-LiV2O5. The gamma structure provides ...
Optimized preparation of alumina based fillers for tuning composite properties
(Ceramics International, 2018)
Alumina based particles were prepared from aluminium chloride hydroxide as starting material by sol-gel technique. One series of particles was doped with ferrous oxide. Both series of particles were calcinated at three ...
The NaxMnO2 materials prepared by a glycine-nitrate method as advanced cathode materials for aqueous sodium-ion rechargeable batteries
(Ceramics International, 2021)
Cathodic material for sodium-ion rechargeable batteries based on NaxMnO2 were synthesized by glycine nitrate method and subsequent annealing at high temperatures. Different crystal structures with different morphologies ...
Sr,Mg co-doping of calcium hydroxyapatite: Hydrothermal synthesis, processing, characterization and possible application as dentin substitutes
(Ceramics International, 2022)
The aim of this study was to investigate the influence of binary Sr, Mg ion-doping compared to the single-ion doping effects on the phase composition and morphology of hydrothermally obtained calcium hydroxyapatite (HAP) ...
Efficient photocatalytic hydrogen production over titanate/titania nanostructures modified with nickel
(Ceramics International, 2019)
Nickel-modified titanate/TiO2 catalysts were prepared by deposition of nickel ions onto hydrothermally prepared titanate supports, followed by hydrogen temperature-programmed reduction. Two different nickel precursors ...
Photoluminescence of Y3NbO7:Eu3+ powders
(Ceramics International, 2022)
Y3NbO7:xEu3+ powders (x = 0.25, 0.5, 0.75, 2, 3, 5, 10 at%) were synthesized by a two-step vibrational milling, alternating with annealing. All the samples crystallize as fluorite-type structure (space group Fm3‾m), with ...
A new endodontic mixture based on calcium aluminate cement obtained by hydrothermal synthesis
(Ceramics International, 2019)
The synthesis of a new endodontic mixture based on calcium aluminate cement is reported. Physico-chemical and mechanical properties of the mixture were investigated before and after various hydration periods. Phase analysis ...
