[Chemical Properties]

3–12mm pieces (fused); used as an evaporated ceramic of 99.9% purity to form a high temp dielectric [CER91] [ΜIT72] [YAM87]
[Description]

Spinel is the magnesium aluminum member of the larger spinel group of minerals.
[Physical properties]

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.
[Uses]

Inert matrix of the transmutation of minor actinides such as Americium.
[Uses]

Magnesium aluminum oxide is used in chemical research, chemicals, pharmaceutical research, pharmaceutical intermediates reagents.
