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

Spinel is the magnesium aluminum member of the larger spinel group of minerals.

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.

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