Sapphire tube precision manufacturing transparent tube Al2O3 crystal wear-resistant high hardness EFG/KY various diameter polishing custom

Short Description:

Sapphire tube, also known as sapphire cylinder or sapphire rod, is a cylindrical structure made of synthetic sapphire material. These sapphire tubes are known for their excellent mechanical and optical properties, making them valuable components in a wide variety of instruments, meters and control devices.
Sapphire tubes made of synthetic sapphire have a unique combination of excellent optical, physical and chemical properties. Sapphire is one of the hardest minerals, with a Mohs hardness of 9 and almost scratch resistance. Sapphire has a melting point of up to 2030 °C. Its excellent thermal conductivity and heat resistance make it ideal for high temperature applications. Its excellent chemical stability and corrosion resistance can withstand harsh environments such as fluorine, plasma, acid and alkaline. In addition, sapphire provides an excellent transmission bandwidth of 0.15-5.5μm between UV and IR. The edge-defined film feeding method (EFG method) enables the production of sapphire tubes of various shapes with minimal or no grinding. All of these unique properties provide a cost-effective solution for applications that require the hardness, scratch resistance, corrosion resistance, heat resistance and optical properties of sapphire tubes.

Sapphire tube has a variety of important roles

1. Hardness and durability: Just like other sapphire components, sapphire tubes are very hard and resistant to scratching, abrasion and wear.
2. Optical clarity: The sapphire tube can be optically transparent and can be used for inspection, visual process or light transmission through the tube.
3. Operating temperature: 1950°C .
4. High temperature resistance: sapphire tube can maintain its strength and transparency even under high temperature conditions, making it suitable for processes involving high temperatures. Sapphire tube can withstand high temperature and high pressure environment, suitable for thermocouple protection in high temperature and high pressure corrosion scenarios such as heavy oil combustion reactor and hydrogen production.
5. Thermal shock resistance: Unlike some materials, sapphire tubes can withstand rapid temperature changes without cracking.
6. Wear resistance and corrosion resistance: the wear resistance and corrosion resistance of sapphire tube make it an ideal choice for chemical equipment and laboratory equipment, which can reduce wear and extend service life.

The following are typical uses of sapphire tubes in these applications

1. Optical Fiber communication: As an optical fiber interface and optical coupling element.
2. Laser device: For optical transmission of lasers.
3. Optical detection: Optical window as an optical detector.
4. Optoelectronic integration: The optical guided wave channel of photoelectric integrated circuit is constructed.
5. Optical imaging: Used in display equipment, camera and other optical systems.
6. Optical applications: Due to its high optical transmittance, sapphire tubes can be used to make optical components, such as curved optical components, curved optical fibers, etc., to meet the high requirements in Micro-LED and OLED display technology.
7. Electronic and Electrical fields: Sapphire tube has high hardness and high insulation, suitable for the production of electronic devices, such as lasers, transistors, etc., can also be metallized to give conductive properties.
8. Other applications: Sapphire pipe can also be used to make a variety of instruments, pumps, gaskets, insulators, etc., widely used in many industrial fields.
