For the past 15 years single crystal sapphire has been at the cutting edge of semiconductor technology. 

A combination of unique chemical, physical, optical ａnd mechanical properties make sapphire the best choice for a broad spectrum of laboratory ａnd industrial applications.
• Chemical resistance.
Sapphire is highly inert ａnd resistant to attack in most process environments including hydrofluoric acid ａnd the fluorine plasma applications commonly found in semiconductor wafer processing (NF3, CF4).

• Mechanical properties.
Sapphire is characterized by high toughness ａnd solidity, ａnd demonstrates excellent resistance in different environments ranging from cryogenic to over 1500°C. Due to this characteristics combined with chemical stability sapphire is widely used in medicine: endoscope ａnd probe lenses, needles for thermal treatment of tumors, scalpels etc.

• Electrical properties.
Sapphire provides a high, stable dielectric constant with the electrical insulation required for LED, RF ａnd microwave applications.

• Optical transmission.
Sapphire is characterized by high transmission in the range of UV to near IR. Given the chemical stability, high temperature ａnd high pressure resistance sapphire is the preferred choice for window / viewport applications in high performance vacuum systems, furnaces, deep sea cameras, fire alarm systems etc.

• Surface properties.
Sapphire can be polished to very high flatness ａnd smoothness for substrate applications ａnd precision mechanical components.

• Thermal properties.
With a melting point over 2000°C, ａnd high thermal conductivity sapphire is often used in many harsh process environments.

• Wear properties.
With high hardness ａnd transparency, sapphire is used for scratch proof windows in high wear applications ａnd for precision mechanical components.
