single crystal sapphire

Sapphire(a-Al2O3) is widely used in many fields from its excellent characteristics, in particular chemical resistance, thermal conductivity, hardness, transparency. Namiki grows single crystal sapphire by EFG method, featuring any desired section forms can be obtained.
Variously-shaped Nano-step structures can be formed on the Sapphire wafer surface, and have been expected to be used as the height standard sample for SPM and Immobilization plate for observing biomaterials.
1. High-hardness - abrasion resistance
2. Transparency
- in the range from ultraviolet to infrared light (200-7000nm)
3. Chemical resistance and heat resistance
- resist almost all kinds of acid and alkaline, heat up to 2000 ºC.
4. Suitable for the application of insulation
property required.
1. Growth of sapphire wafers with large diameter
2. Controllability of crystal orientation
