Spinel is the magnesium aluminum member of the
larger spinel group of minerals.
3–12mm pieces (fused); used as an evaporated ceramic of 99.9% purity to form a high temp dielectric [CER91] [ΜIT72] [YAM87]
Monolithic, transparent spinel is also used in optical
applications, such as windows for pressure vessels and
bulletproof vehicles.
Among the crystalline compounds, the spinel oxides
present a large range of interesting electrical, magnetic
and optical properties. The magnesium–aluminum
spinel, MgAl2O4, in particular has been comprehensively
studied and previous works point out a high
melting point (2135 °C), a high hardness (7.5–8 Mohs),
and interesting thermal and optical properties.
Inert matrix of the transmutation of minor actinides such as Americium.
Magnesium aluminum oxide is used in chemical research, chemicals, pharmaceutical research, pharmaceutical intermediates reagents.
