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.
