Crack-healing in spinel (MgAl2O4) ceramic

Materials Science and Engineering: A, 2015
Abstract This paper reports the crack-healing behavior in spinel ceramic. Spinel nanopowder was synthesized via mechanical activation with subsequent annealing of magnesium carbonate and aluminum hydroxide. The produced nanopowder was uniaxially pressed and then sintered at 1200 °C for 1 h.

Magnesium Aluminate (MgAl2O4) by XPS

Surface Science Spectra, 1994
The XPS spectra of materials containing both magnesium and aluminum can exhibit a number of spectral artifacts when using a Mg Kα x-ray source. These artifacts are easily observed in XPS spectra of magnesium aluminate (MgAl2O4, also known as magnesium aluminum oxide), which are presented in this article. For example, the Al 2p peak is overlapped by the

Raman study of MgAl2O4–FeAl2O4 and MgAl2O4–MgFe2O4 spinel solid solutions

2015
Spinels oxides are minerals or synthetic materials which are nowadays attracting considerable interests because of their physical and chemical properties. Ten synthetic spinels belonging to the MgAl2O4–FeAl2O4 solid-solution and four synthetic spinels belonging to the MgAl2O4–MgFe2O4 solid-solution have been studied by Raman spec-troscopy to verify the

Low temperature ESR of MgAl2O4 nanoceramics

AIP Conference Proceedings, 2019
MgAl2O4 nanoceramics was synthesized by thermobaric hardening. The six narrow lines in the ESR spectrum are the hyperfine structure of the uncontrolled Mn2+ impurity. Thermobaric hardening of nanoceramics leads to the formation of paramagnetic F+ centers.
