Single-Crystal Sapphire (Al2O3)
It is a single crystal of alumina and is a transparent material
Sapphire, commonly known for the gemstone of the same name, is a single crystal alumina that creates a high-purity, high-performance material. Due to its excellent mechanical properties and chemical stability, it is applied to both mechanical and precision parts. In addition, it is a transparent material and has high optical properties in a wide wavelength range from infrared rays to near-ultraviolet rays. It is easier to mass produce than diamond and has better properties than quartz. It is used in optical components such as sensors and analytical instruments, contributing to longer component life and higher equipment productivity.
- Important property :
- Insulation
- Wear Resistance
Features
-
High Strength, High Rigidity, High Anti-Abrasion, High Anti-Heat, High Anti- Corrosion Characteristics, and High Anti-Plasma CharacteristicsBecause of these characteristics, single crystal sapphire is widely used for precision mechanical parts.
-
Stable Dielectric Constant, Very Low Dielectric Loss, Good Electrical InsulationSingle crystal sapphire is used as a material for substrates in super-high frequency regions. It is also used as an insulation material and microwave window. Single crystal sapphire has become indispensable in the electronics industries.
-
Excellent Light TransmissionSingle crystal sapphire is used for various kinds of vacuum equipment, windows in reaction furnace, scanner windows and caps for optical communication due to its excellent mechanical characteristics and heat resistance.
-
Good Thermal Conductivity and High Heat ResistanceExcellent thermal conductivity at low temperatures allows single crystal sapphire as a transparent material to be used in many diverse fields requiring thermal conduction and heat radiation.
Crystal Comparison
Without voids or grain boundaries, it exhibits excellent mechanical properties.
Crystal Orientation of Sapphire
Characteristics change depending on the crystal orientation.
