Synthesis of MgAl2O4 nanopowders

Inorganic Materials, 2011
A procedure has been developed for the synthesis of MgAl2O4 nanopowders with a characteristic particle size of 10–40 nm. Translucent hydrous xerogels have been synthesized as precursors to MgAl2O4. The synthesized magnesium aluminum spinel nanopowders are promising for the fabrication of optical ceramics.

Synthesis, microstructure and oxidation of Co-MgAl2O4 and Ni-MgAl2O4 nanocomposite powders

Nanostructured Materials, 1996
MgAl2O4-CoAl2O4 and MgAl2O4-NiAl2O4 solid solutions are synthesized by combustion in urea of the appropriate metal nitrates. The selective reduction in hydrogen of these oxides gives rise to a dispersion of nanometric Co or Ni particles in the spinel matrix. The reduction of the Co2+ and Ni2+ ions is complete at 900 and 1000 °C respectively.

Crystallization of MgAl2O4 and its effect on strengthening-toughening behavior in TiAlN/MgAl2O4 nanomultilayers

Vacuum, 2017
Abstract TiAlN/MgAl2O4 nanomultilayers with different MgAl2O4 layer thickness (lMgAl2O4) were fabricated. Studies show that under the template effect of TiAlN layers driven by interfacial energy minimization, amorphous MgAl2O4 crystallized and grew epitaxially with TiAlN layers, forming high-quality layered structure and coherent interface at low ...

A Density Functional Study of Interactions at the Metal–Ceramic Interfaces Al/MgAl2O4 and Ag/MgAl2O4

physica status solidi (a), 1998
Ab-initio density functional calculations were performed on the geometric and the electronic structures of coherent cube-on-cube interfaces between spinel (MgAl 2 O 4 ) and the two metals Al and Ag. The calculations were carried out in the local density approximation (LDA) employing norm-conserving pseudopotentials and a mixed basis set of plane waves ...
