In this work, a transparent nanostructured ceramic magnesium aluminate spinel (MgAl2O4) was fabricated by Spark Plasma Sintering (SPS) from commercial nano-powders at different temperatures (1300, 1350 and 1400 °C). The sintered samples were thoroughly examined to assess their microstructural, optical, mechanical properties. Various techniques such as SEM, AFM, spectrophotometer with an integra...

The radiation damage produced by energetic heavy ions in several ceramic oxides was characterized by different methods: thermoluminescence, optical absorption, fluorescence and electron paramagnetic resonance. Following ion irradiation, the thermoluminescence intensity of all the samples is shown to decrease. This can be related to the observed rise of the optical absorption in the whole wavele...

Nanocrystalline magnesium ferrite is synthesized by high-energy ball milling. The formation of nanocrystalline ferrite phase is observed after 3 h of milling and its content increases with milling time. The structural and microstructural evolution of the nanophase have been studied by X-ray powder diffraction and the Rietveld method. After 3 h of milling, ferrite phase (mixed spinel) nucleates ...

This work devotes to investigate synthesis and electrical properties of spinel MgCo2O4 that is considered as a candidate of the cathode materials of magnesium-ion batteries in future. Samples were synthesized by two types of techniques: solid-state reaction and wet process. The crystal structures of the samples were analyzed by X-ray diffraction, and their electrical conductivities were obtaine...
