The transparent ceramic materials made from polycrystalline spinel have excellent transmission characteristics from visible light to near-infrared rays (1 μm band) and medium-infrared rays (3–5 μm band). The machinability is better than that of single crystal sapphire. These spinels are suitable for applications in electronic devices for their low thermal expansion coefficient, high heat conductivity, and superb heat dissipation performance.
