Sapphire Tube 99.999% AL2O3 Polished High Hardness Ion Source Customization EFG KY
Sapphire tubes are the best high-pressure containers
and transport plumbing for many high-pressure systems. A sapphire tube can handle extreme pressures while allowing for safe observation and spectral analysis of fluids and gasses. Sapphire tubes can be used in hostile environments to house sensitive sensors, protecting the sensors against pressure and mechanical abuse. Sapphire rods are superior for rod bearing and standoff applications that involve high abrasion and wear while maintaining dimensional stability.
A sapphire tube is the ideal lamp material for UV and IR lamps because it can go far deeper into the UV and IR than any other lamp material. With its thermal robustness, a sapphire lamp can be exposed to extreme plasmas and temperatures, far greater than any other material, and continue to transmit high-powered UV, visible, and IR for years with no degradation.
Hardness: Sapphire is one of the hardest materials, second only to diamond, making it highly scratch-resistant and durable.
Transparency: Sapphire has excellent optical properties, allowing light to pass through with high clarity. This makes sapphire tubes ideal for applications requiring optical transmission.
Chemical Resistance: Sapphire is highly resistant to chemical corrosion, making it suitable for use in harsh environments.
Temperature Resistance: Sapphire can withstand high temperatures, making it suitable for applications where heat resistance is important.
Electrical Insulation: Sapphire is an excellent electrical insulator, which is beneficial in various electronic and semiconductor applications.
