Low temperature synthesis of magnesium oxide and spinel powders by a sol-gel process
Materials Research, 2010 Magnesium oxide and magnesium aluminate (MgAl2O4) spinel (MAS) powders have been synthesized by a simple aqueous sol-gel process using citrate polymeric precursors derived from magnesium chloride, aluminium nitrate and citrate.

Sonochemical preparation of high surface area MgAl2O4 spinel
Ultrasonics Sonochemistry, 2009 High surface area MgAl(2)O(4) has been synthesised by a sonochemical method. Two kinds of precursors were used, alkoxides and nitrates/acetates and in both cases nanostructured MgAl(2)O(4) was obtained. The effect of the addition of a surfactant during the sonication, cetyl trimethyl ammonium bromide, was also investigated.

Efficient determination of alloy ground-state structures [PDF]
, 2014 We propose an efficient approach to accurately finding the ground-state structures in alloys based on the cluster expansion method. In this approach, a small number of candidate ground-state structures are obtained without any information of the energy ...

Stabilization of MgAl2O4 spinel surfaces via doping [PDF]
Surface Science, 2016 Abstract Surface structure of complex oxides plays a vital role in processes such as sintering, thin film growth, and catalysis, as well as being a critical factor determining the stability of nanoparticles. Here, we report atomistic calculations of the low-index stoichiometric magnesium aluminate spinel (MgAl2O4) surfaces, each with two different ...
