Description of Sapphire Tube:
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.
The character of Sapphire Tube:
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.
