Synthesis, characterization and ionic conductivity of MgAl2O4 [PDF]

, 2015
Magnesium aluminate nanoparticles have been synthesized by a citrate sol-gel route. X-ray diffraction and IR spectroscopy study confirmed the formation of MgAl2O4 cubic spinel structure without presence of any secondary phase.

Microstructural characterization of in-situ MgAl2O4 nanoparticles reinforced Al–2Mg–1Si composite produced using the ultrasonic assisted stir casting process

Journal of Materials Research and Technology
The ceramic particle reinforced Aluminium Matrix Composites (AMCs) lead to a reduction in ductility due to the restricted plastic flow of the matrix. The present work shows an enhancement in tensile properties without considerable loss in ductility by ...

Dilatometric characteristics of weakly sintered ceramics

Chimica Techno Acta, 2022
Thermal expansion of refractory ceramics CaZrO3, MgAl2O4, La2Zr2O7 and YSZ-12 was studied. The samples of the complex oxides were synthesized by solution combustion synthesis with glycine; the fuel:oxidant ratio was varied depending on the character of ...

Nanocubes and Cuboctahedra: Entropic Stabilization Versus Thermal Segregation in Rock Salt‐ and Spinel‐Type Multinary Oxides from Spray‐Flame Synthesis

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Spray‐flame synthesis enables highly flexible and scalable production of multinary and high‐entropy oxide nanoparticles due to high synthesis temperatures with subsequent quenching. Temperature‐dependent in situ diffraction of as‐synthesized materials clearly reveals entropy stabilization in rock salt lattices, while spinels—featuring tetrahedral and ...

Processing strong MgAl2O4 ceramics via zirconia transformation toughening

Journal of Materiomics
The applications of magnesium aluminate spinel (MgAl2O4) ceramics often require optical transparency, suggesting minimal macroscopic flaws otherwise too strong light scattering would make them opaque.

Spin‐Polarized Magnetic Metal Electrodes for Magnetic Tunnel Junctions

MetalMat, EarlyView.
This perspective surveys spin‐polarized magnetic metal electrodes for magnetic tunnel junctions, systematically covering conventional ferromagnets, collinear/noncollinear antiferromagnets, and emergent altermagnets. It compares tunneling polarization origins across these classes and emphasizes that effective electrode polarization is a momentum ...

Analyses of the Deformability and Chemistry of Non‐Metallic Inclusions in QT Steels With Increased Recycling‐Induced Tramp Element Content

steel research international, EarlyView.
This work uses high‐temperature dilatometry to examine how the tramp elements Cu, Ni, and Sn affect the deformability of non‐metallic inclusions and matrix in quench‐and‐temper steel. Mg‐bearing inclusions deform less than Mg‐free ones. Copper lowers formability. Nickel increases deformability.

From Tetracycline to Sulfamethoxazole: Photocatalytic Degradation and Mechanistic Insights in Aquatic Environments

Rare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT The pollution caused by antibiotics to aquatic ecosystems is becoming increasingly serious, thus more effective treatment methods are urgently required. Although the photocatalytic degradation behavior of tetracycline (TC) is relatively well understood, sulfamethoxazole (SMZ), an emerging pollutant originating from large‐scale livestock ...

MOVPE growth of GaN and LED on (111) MgAl2O4

, 1998
The growth of wurtzite GaN by low-pressure metalorganic vapor-phase epitaxy on (1 1 1) magnesium aluminate (MgAl2O4) substrates have been studied. The morphological, crystalline, electrical and optical properties are investigated.
