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

Tribological Behaviour of Transparent Spinel (MgAl2O4)

2022
The wear behaviour of transparent magnesium aluminate (MgAl2O4) was investigated for unlubricated sliding against chrome steel balls under different load (5, 10, and 15 N) conditions. The sliding speed and sliding distance were retained constant, i.e., 260 mms-1 and 157 m, respectively.

Decrease of the MgAl2O4 formation temperature

1997
Mixtures of Al2O3 and (MgCO3)(4) . Mg(OH)(2) . 5H(2)O, mechanically activated by intense grinding in a laboratory vibrating mill for up to 120 min, were additionally heat treated from 800 to 1250 degrees C, It was shown that more intense particle size reduction of the crystallites of basic MgCO3 from 39 to 13 nm took place during activation, while the ...
