The cationic magnesium moiety of magnesium organohaloaluminate complexes, relevant to rechargeable Mg battery electrolytes, typically takes the thermodynamically favourable dinuclear [Mg2Cl3](+) form in the solid-state. We now report that judicious choice of Lewis donor allows the deliberate synthesis and isolation of the hitherto only postulated mononuclear [MgCl](+) and trinuclear [Mg3Cl5](+)...

Integrated temperature-humidity-sensitive thick-film structures based on spinel-type semiconducting ceramics of different chemical compositions and magnesium aluminate ceramics were prepared and studied. It is shown that temperature-sensitive thick-film structures possess good electrophysical characteristics in the region from 298 to 358 K. The change of electrical resistance in integrated thic...

Motivated by the search of new materials for optically stimulated luminescence (OSL) dosimeters, magnesium aluminum spinels with different Mg:Al ratios were investigated. Powders prepared via co-precipitation method 1:2 (stoichiometric), 1.5:2 (MgO-rich) and 1:3 (Al2O3-rich) calcined at 1000 °C in air 2 h. A higher level structural disorder was found powders than single crystal as determined X-...

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 ...
