Sapphire Tube Benefits |
| |
Sapphire tubes made of synthetic sapphire possess a unique combination of excellent optical, physical, and chemical properties. As one of the hardest minerals, ranking 9 on the Mohs scale, sapphire is virtually scratch-resistant. It has a high melting temperature of 2030°C, making it well-suited for applications requiring extreme heat resistance. Its superior thermal conductivity further enhances its suitability for high-temperature applications. |
| Sapphire's exceptional chemical stability and corrosion resistance allow it to withstand harsh environments, including exposure to fluorine plasma, acids, and alkalis. Additionally, sapphire tubes offer excellent transmission across a wide bandwidth, from UV to IR, spanning 0.15 to 5.5 µm, making them ideal for various optical applications. |
| The Edge-Defined Film-Fed Growth (EFG) method enables the production of sapphire tubes in various shapes with minimal or no grinding. This manufacturing technique ensures precision and consistency, meeting the stringent requirements of advanced applications. |
| These unique properties make sapphire tubes a cost-effective solution for applications demanding hardness, scratch resistance, corrosion resistance, heat resistance, and superior optical performance. Sapphire tubes are indispensable in industries where durability and optical clarity are paramount. |

| Sapphire Tube Applications |
| Sapphire tubes are ideal for a wide range of industrial applications, including semiconductor processing, test and analytics, and lamps and lamp envelopes. In testing and analytics, sapphire tubes are used for biological and chemical sample analysis, Nuclear Magnetic Resonance (NMR) spectroscopy, mass spectroscopy, plugged tubes, thermo-optic temperature measurement, and inline petroleum processing analysis. Additionally, they are employed as plasma containment tubes, process gas injectors, thermocouple protection, water treatment, and high-intensity lamps. |
| Sapphire tubes exhibit high mechanical strength, making them suitable for housing sensors or lasers in thick-walled designs to protect them from extreme pressure. Both the outer and inner diameters can be polished to enable laser light emission and reflected light measurement, making sapphire tubes ideal for high-pressure systems and vacuum atmospheres. |
| Due to their chemical inertness and corrosion resistance, sapphire tubes are the preferred material for plasma containment. This resistance allows them to withstand extreme plasmas without generating particles, maintaining their integrity and performance in harsh environments. |
| Sapphire tubes retain their high strength and do not change shape under high temperatures and pressures. With high thermal stability, good thermal conductivity, and excellent transparency, sapphire tubes are the ideal material for supporting UV, visible, and IR applications in hostile environments, such as high-intensity lamps. |
| HYT Sapphire Optics supplies "as grown," fine-ground, and polished sapphire tubes for a wide range of applications. Custom shapes, including angles, slots, holes, and bonded configurations, are available to meet precise customer specifications. Our achievable specifications for sapphire tubes include inner diameters starting at 0.40mm, wall thicknesses up to 20mm, lengths up to 600mm, and surface quality up to 40/20. |
