Combustion synthesis, characterization and sintering behavior of magnesium aluminate (MgAl2O4) powders

Solution combustion synthesis of α-cordierite

“…Considering that triethylenetetramine is able to generate after annealing at 700 • C spinel powders with specific surface area as high as 175 m 2 /g [29], in the case of sam- …”

Correlation between structural and electrical properties of Mg1−2xZnxNixAl2O4 (x=0.0–0.5) ceramic nanomaterials synthesized by a urea assisted microwave combustion method

“…The DC electrical resistivity and the dielectric measurements were carried out with sample pellets of 13 mm diameter and 1 mm thickness. The absence of any extra peaks in these patterns indicates that the synthesized samples consist of purely single-phase of MAS [22,23]. The lattice constant (a) was calculated from the X-ray powder diffraction data using following equation [24]:…”

Thermal stability and microstructure characterization of MgAl2O4 nanoparticles synthesized by reverse microemulsion method

“…The preparation of MgAl 2 O 4 powders by classical solid-state reaction requires a high calcination temperature (~1600 °C) and long reaction time, so that the powders suffer from low sinterability and agglomeration, which makes it difficult to fabricate transparent ceramics 5 . Therefore, some wetchemical methods like co-precipitation 6 , mechanochemical method 7 , molten salt method 8 , citrate-nitrate combustion 9,10 and sol-gel process 11,12 have been used for the synthesis of nanosized MgAl 2 O 4 . Although nanosized particles could be produced by means of these synthesis routes, it is hard to achieve the falicity of tuning particle size and morphology.…”
