Sapphire rods tips customized polished optical rods premium micro
sapphire rods
Sapphire rod is a cylindrical material made of high purity single
crystal sapphire (Al₂O₃), which is widely used in semiconductor,
photoelectric and scientific research fields due to its excellent
physical and chemical properties. Its high hardness, high
temperature resistance, corrosion resistance and excellent optical
properties make it an ideal material for semiconductor
manufacturing and high-end devices.
1. High hardness and wear resistance: sapphire has a Mohs hardness of 9, second only to diamond, which
can resist mechanical wear and prolong service life.
2. High temperature resistance: sapphire rod can work stably in high temperature environment below
2000°C, suitable for semiconductor high temperature process.
3. Excellent chemical stability: Strong corrosion resistance to acids, alkalis and most chemical
solvents, suitable for harsh chemical environments.
4. High transmittance: Excellent optical transmittance in the ultraviolet to infrared
band, suitable for optical and photoelectric applications.
5. Low coefficient of thermal expansion: Low coefficient of thermal expansion ensures dimensional stability
in high temperature environment and reduces deformation caused by
thermal stress.

environments.
1. Q: What are sapphire rods used for?
A: Sapphire rods are used in semiconductor manufacturing, LED
production, and high-temperature experiments due to their high
hardness, thermal stability, and chemical resistance.
2. Q: Why are sapphire rods preferred in high-temperature
applications?
A: Sapphire rods are preferred for high-temperature applications
because they can withstand temperatures up to 2000°C while
maintaining structural stability and chemical inertness.
