Premium Sapphire Tube with High Surface Quality High Anti-corrosion and EFG/KY Growth Technology

Sapphire Tube is a type of transparent single-crystal alumina material renowned for its exceptional chemical stability and superior mechanical, thermal, and optical properties. When compared to commonly used transparent materials like glass and quartz, Sapphire Tube outperforms them significantly.

Sapphire boasts outstanding optical clarity, physical resilience, and chemical inertness. It stands as the hardest oxide crystal, retaining its strength and resistance even under elevated temperatures. Moreover, it exhibits a wide transmission spectrum, excellent electrical insulation properties, and efficient thermal conductivity, particularly at low temperatures. Its remarkable attributes include high hardness, strength, and resistance to extreme temperatures, making it capable of withstanding harsh chemical environments such as fluorine plasma, acids, and alkaline solutions.

Sapphire tubes stand out as exceptional high-pressure vessels and conduits in numerous high-pressure systems. With their ability to withstand extreme pressures, they provide a secure means for observing and spectrally analyzing fluids and gases.

In hostile environments, sapphire tubes serve as protective enclosures for sensitive sensors, shielding them from pressure and mechanical stress. Even under the harshest conditions, supported sapphire tubes maintain their structural integrity, remaining unchanged in shape at temperatures up to 2000°C while experiencing minimal reduction in mechanical performance. They excel in applications such as high-temperature combustion chambers, gas processing, and lamp construction.

Sapphire tubes combine optical transparency, chemical inertness, thermal endurance, and mechanical durability, making them indispensable for medical devices, industrial instrumentation, semiconductor fabrication, aerospace systems, and optical technologies.

Utilized as insulating and observation tubes in semiconductor process equipment. Resistant to plasma, chemical etchants, and high temperatures, making them suitable for CVD, PVD, and plasma etching systems. Provide optical access for process monitoring and sensor protection in vacuum or high-pressure environments.

Employed as light guides, laser conduits, or protective housings in laser machining, spectroscopy, and illumination systems. The wide transmission range from 190 nm (UV) to 5 µm (IR) makes sapphire tubes ideal for UV and IR optical applications.

Applied in endoscopy systems, laser delivery systems, and fiber-optic probes due to sapphire's biocompatibility and optical clarity. Used as protective tubes for sensors, thermocouples, and analytical instruments exposed to reactive gases or liquids. Sapphire's smooth inner surface prevents contamination and particle buildup, ensuring clean optical transmission.
