Sapphire wafers are widely used in advanced technologies due to their excellent mechanical strength, high thermal conductivity, wide optical transparency range, and outstanding chemical resistance. Their main applications include:
Semiconductor Industry
Used as substrates for GaN (gallium nitride) and other III-V compound semiconductors in the production of LEDs, laser diodes, and high-power/high-frequency electronic devices.
Optoelectronics
Essential for manufacturing blue, green, and white LEDs.
Applied in optical windows, lenses, and laser systems due to their high transparency from ultraviolet (UV) to infrared (IR) ranges.
Microelectronics
Serve as insulating substrates in RFICs (radio frequency integrated circuits) and IC applications, enabling high-performance communication devices.
Aerospace and Defense
Used for durable optical windows, sensor covers, and protective layers thanks to their extreme hardness and resistance to harsh environments.
Consumer Electronics
Applied in protective covers for smartphone camera lenses, fingerprint sensors, and wearable devices due to scratch resistance and optical clarity.
Medical and Scientific Instruments
Used in diagnostic optics, endoscopes, and high-precision scientific instruments requiring durability and transparency.
