Foamability of MgAl2O4 (Spinel)-Reinforced Aluminum Alloy Composites

, 2011
A novel foamable aluminum alloy has been developed. It contains sub micron sized MgAl2O4 spinel particles that are generated in situ by a reaction of SiO2 with a molten Al Mg alloy.

Magnetic properties of titanomagnetites containing spinel (MgAl2O4).

Journal of geomagnetism and geoelectricity, 1981
Magnetic properties of titanomagnetites containing spinel have been studied. Variations of magnetization at room temperature and Curie point have been measured as a function of α, the mole fraction of ulvospinal in titanomagnetite series, and β, the mole fraction of spinel. Magnetization at 20°C and Curie point decrease with increasing α and β.

Morphological and structural characterization of spinel MgAl2O4

, 2019
Magnesium aluminate has spinel structure and very good mechanical, chemical, and thermal properties. Owing to these properties, it has a wide range of applications including refractory ceramics, optically transparent ceramic windows and armors. Its low dielectric permeability and low loss tangent enable its using for integrated electronic devices, as ...
