Customizable sapphire tube transparent sapphire pipe hardness Mohs 9.0 high wear resistance
Product overview
Sapphire tubes is a glass tube made by sapphire (Al2O3), a synthetic stone with great physical, optical, mechanical and chemical qualities. Its hardness is Mohs 9.0, the second hardest only after the hardest diamond. It can have good performance under high pressure, high temperature and vacuum environments owing to its high melting point, which is 2053℃, great thermal conductivity, and strong heat resistance. Thus, sapphire tube is an ideal material for lots of application fields.
Sapphire tubes have a good transmittance of light, which makes it a suitable material to be used in optical fields. Sapphire tube has good light transmission in the spectral range of 200nm to 5500nm, and the infrared transmittance almost does not change with the temperature, and the working temperature can reach 1900℃, which make it great to carry out spectral analysis in the optical field.
Sapphire tube also has lots of advantages, including its inherent resistance to high temperature and chemical environments. It has good acid and corrosion resistance. So, it is ideal for a variety of analytical instruments. Therefore, sapphire tubes are ideal materials in many range of applications.

Product properities
1. High hardness: Sapphire tubes hardness is Mohs 9.0 which is sencond hardness only to the hardnest diamond, making sapphire tubes a good wear resistance and scratching resistance and can stay stable in relative hard condition.
2. Good wear resistance: Owing to sapphire tube's high hardness, sapphire tubes' wear resistance is very great. Sapphire tubes can maintain structual integrity and surface finishment after a long term use.
3. Good chemical performance: Sapphire tubes have a good chemical performance, they have a resistance to chemical corrosion, they are a good aterial against acid and corrosion.
4. High temperature resistance: Sapphire tubes's melting point is 2053℃, their highest working temperature is 1950℃. So sapphire tubes can be applied in high temperature condotions
5. Wide use: Sapphire tubes can be used in extensive fields, from laser systmes, optical instrements, high temperature fumaces to chemical instrument processing.
Product applications
1.Optical Instruments: Sapphire tubes have a good light transmittance with minimal light loss and distortion, making it widely used as optical windows or lenses and optical instruments such as spectrometers, cameras, and telescopes.
2.High-Temperature Furnaces: Sapphire tubes highest working temperature is up to 1950℃, shows a great resistance to high temperature and stays steady in high temperature, so it can be protective sheath for temperature probes, thermocouples, and heating elements, to making it in extreme high temperature without degradation.
3.Semiconductor Manufacturing: Sapphire tubes can be used in semiconductor manufacturing processes as part of equipment for handling and processing semiconductor wafers, to provide mechanical support, chemical resistance, and electrical insulation.
4.Laser Systems: Sapphire tubes can be widely used in laser systems as a protective enclosure for laser components, ensuring optical clarity and stability under high-power laser beams.
Duing to sapphire tubes high hardness of Mohs 9.0, high wear resistance, high pressure resistance and other excellent mechanical performance, chemical performance and optical performance, sapphire tubes can be also applied in these fields: optical instrument, chemical processing equipment, biomedical devices and research and development.
