Description of Sapphire Tube:
Sapphire tubes are transparent components made by cold-processing
single-crystal sapphire. They possess characteristics such as
corrosion resistance, high-temperature resistance, and
high-pressure resistance. Under equal conditions, their corrosion
resistance is 1000 times that of quartz, their pressure resistance
is 4 times that of quartz, and their high-temperature resistance
exceeds that of quartz by over 600°C.
In the chemical industry, the use of sapphire tubes can effectively
mitigate leakage and rupture risks, enabling long-term usage. They
offer a great cost-performance ratio, which is why an increasing
number of manufacturers are opting for them.
The Character of Sapphire Tube:
1. High Strength, High Rigidity, High Anti-Abrasion, High
Anti-Heat, High AntiCorrosion Characteristics, and High Anti-Plasma
Characteristics.
Because of these characteristics, Sapphire tubes are widely used for precision mechanical parts.
2. Stable Dielectric Constant, Very Low Dielectric Loss, Good
Electrical Insulation.
Sapphire tubes are used as a material for substrates in super-high frequency
regions. It is also used as an insulation material and microwave
window. Sapphire tubes have become indispensable in the Electronics industry.
3. Excellent Light Transmission.
Sapphire tubes are used for various kinds of vacuum equipment, windows in reaction
furnaces, scanner windows, and caps for optical communication due
to its excellent mechanical characteristics and heat resistance.
4. Good Thermal Conductivity and High Heat Resistance.
Excellent thermal conductivity at low temperatures allows Sapphire tubes are as a transparent material to be used in many diverse fields
requiring thermal conduction and heat radiation.

FAQ:
1.Q:What is sapphire coating?
A:It has better impact resistance than mineral glass and in
practice sapphire crystal can only be scratched with diamond. Thus,
a thin layer of sapphire on top of the mineral crystal glass
greatly increases its impact resistance and is not easily
scratched.
2. Q: Is sapphire better than acrylic?
A: Although sapphire crystal appears on most high end watches for
the last 30 years, acrylic still appears on the vast majority of
low cost timepieces. Sapphire has superior scratch resistance. In
fact a rare few products like diamonds exceed sapphire on the Mohs
hardness scale.
