Abstract of Sapphire tubes

 

 

 

Sapphire optical glass tube 99.999% Al2O3 high hardness 9.0 polished customized size

 

A ​​sapphire tube​​ is a transparent tubular material manufactured from high-purity monocrystalline sapphire (Al₂O₃) through precision processing. It combines exceptional optical, mechanical, and chemical performance. Its core features include ​​ultra-high hardness (Mohs hardness of 9)​​, ​​extreme thermal resistance (operational stability up to 2000°C)​​, ​​corrosion resistance (stable in strong acids and alkalis)​​, and ​​broad-spectrum transparency (0.15–5.5 μm wavelength range)​​. Sapphire tubes are widely utilized in advanced industries such as semiconductors, chemical engineering, optical instruments, and medical devices

 


 

Key Features of Sapphire tubes

1. ​​High Transparency and Optical Performance​
Sapphire tubes exhibit excellent light transmittance (0.15–5.5 μm) with minimal optical loss (<0.1–0.3 dB/cm), making them ideal for laser transmission, optical windows, and fiber optic connectors.

 


2. Extreme Environmental Durability​

· ​​Thermal Resistance​​: Sustained operational temperatures up to 1600–2000°C, with short-term tolerance up to 2050°C.

· ​​Chemical Resistance​​: Superior to quartz in resisting acids, alkalis, fluorine, and plasma.

· ​​Mechanical Strength​​: Compressive strength 4x higher than quartz, suitable for high-pressure reactors and precision instruments.

 

​3. Dimensional Customization and Precision​

​· Customizable Sizes​​: Outer diameter (3–300 mm), inner diameter (0.8–25 mm), and length (up to 250 mm).

· ​​Precision Machining​​: Utilizes CNC milling, diamond tools, and Edge-Defined Film-Fed Growth (EFG) methods to achieve concentricity errors <0.02 mm and surface roughness ≤Rz0.1.
