.EFG Sapphire Tubes

    As one of the hardest substances known, sapphire has an ultra-high melting point (2050°C), excellent physical, chemical and optical properties, and is widely used in various harsh working environments. The sapphire tubes provided by Optic-Well have the following characteristics:

 1. Excellent heat resistance and pressure resistance, ultra-high use temperature up to 1950 °C;

 2. High purity better than 99.995%, ensuring that the performance of sapphire tube is close to the ideal value;

 3. With Mohs’9 hardness grade, outstanding wear resistance;

 4. The EFG Method as grown sapphire tube, different from the sapphire tube made of mechanical processing and high-temperature alumina powder sintering, has 100% airtight performance, will not penetrate residual gas, and is resistant to chemical gas corrosion.

   Typical uses for sapphire tubes as below:

1. semiconductor processing; In the semiconductor processing industry, sapphire tubes perform better than quartz, ceramic, and silicon carbide tubes, and applications for sapphire tubes include: 

• Plasma sealed tubes 

• Process gas injectors 

• Thermocouple protection components

2. Testing & Analysis Sapphire tubes can be used in a variety of analytical instruments, including:

 • NMR spectroscopy 

 • Fiber optic temperature measurement 

 • In-line petroleum process analysis 

 • Mass spectrometry analysis 

 • Biological and chemical sample analysis

 • Optical communication test analysis

3. Lighting fixtures Sapphire lamps, which can transmit visible light, infrared or ultraviolet light, are often used under high pressure at ultra-high temperatures, including: 

 • Infrared countermeasures 

 • UV sterilization 

 • Flash lamps 

 • High brightness lamps.
