The sapphire tube is a high-performance material pipe made of single-crystal sapphire with excellent physical and chemical properties.
Sapphire (aluminium oxide single crystal) has extremely high hardness, second only to diamond, and has strong wear resistance and scratch resistance.
Sapphire tubes also have excellent high-temperature and chemical corrosion resistance and can maintain stability in extreme environments. This makes sapphire tubes important in high-temperature equipment, optical instruments, medical equipment and other fields.
In addition, the high light transmittance of sapphire makes it excellent in optical applications, especially in the ultraviolet and infrared ranges and can transmit light of specific wavelengths without being affected.
Sapphire tubes are widely used in precision manufacturing, aerospace, and semiconductor industries, and are indispensable key components in many high-tech fields.

Sapphire tube has high mechanical strength. The sapphire tube with thick wall can be used to accommodate the sensor or laser and protect the sensor or laser from extreme pressure. Its outer diameter and inner diameter can be polished to realize laser emission and reflected light measurement. Sapphire tubes are ideal for high-pressure systems and vacuum applications.
Sapphire tube is an ideal material for a wide range of industrial applications, such as semiconductor processing, testing and analysis, lamps, and lamp housings. Typical applications of testing and analysis include biological and chemical sample analysis, nuclear magnetic resonance spectroscopy, mass spectrometry, blocked tube, Thermo optical temperature measurement, and online petroleum processing analysis. Sapphire tubes can also be used as plasma containment tubes, process gas injectors, thermocouple protection, water treatment and high-intensity lamps.
Sapphire tube maintains its high strength and shape under high temperature and high pressure. Sapphire lamp tube has high thermal stability, good thermal conductivity, and excellent transparency. It is an ideal lamp material to support ultraviolet, visible, and infrared applications in harsh environments.
Sapphire tube is the preferred material for plasma protection because of their chemical inertia and corrosion resistance. Chemical resistance enables sapphire tubes to withstand extreme plasma without generating particles.
