Product Description
Product Introduction Of Sapphire Tubes
Sapphire tubes are hollow cylindrical components made from high-purity single-crystal aluminum oxide (Al₂O₃). They feature exceptional hardness, outstanding optical transparency, and excellent resistance to high temperatures and chemical corrosion. Their dense, non-porous structure makes them ideal for observation, sensing, and protection applications in extreme environments.
Working Principle Of Sapphire Tubes
Sapphire is a single-crystal material with a trigonal crystal structure, featuring a Mohs hardness of 9 and excellent thermal stability. Its wide band gap and superior chemical resistance allow it to maintain performance under extreme conditions such as high temperature, pressure, and corrosive environments—making it suitable for use as windows, sheaths, or sensing chambers.
Applications Of Sapphire Tubes
Industrial Inspection Windows: Transparent windows for high-temperature furnaces or plasma chambers.
Optical Fiber Sheathing: Protection of sensitive optical/fiber components in harsh environments.
High-Temperature Sensor Housing: Enclosure for thermocouples or optical temperature sensors.
Medical Devices: Fluid delivery systems or probe housings in high-sterility environments.
Military & Aerospace: Windows and monitoring tubes for missiles or spacecraft.
Q&A Of Sapphire Tubes
Q1: What is the maximum temperature a sapphire tube can withstand?
A1: Sapphire tubes can withstand up to 1600°C in air and over 2000°C in inert or vacuum environments.
Q2: Is sapphire electrically conductive?
A2: No, sapphire is an excellent electrical insulator, suitable for high-voltage applications.
Q3: Is it possible to customize sapphire tubes?
A3: Yes. Please provide specifications such as outer diameter, inner diameter, length, and tolerance—custom quotes will be provided accordingly.
Q4: What is the optical transmission of sapphire tubes?
A4: Sapphire offers high transmittance from UV to IR range (approximately 200nm–5μm), making it suitable for various optical sensing applications.
