High Hardness 34*28*132mm Sapphire Glass Tube High Temperature Resistant

Product Name: Sapphire Glass Tube
Specification and Dimensions: Φ34*28*132mm

Sapphire glass tube is a high hardness, high temperature resistant and corrosion-resistant transparent single-crystal alumina (Al₂O₃) tube, commonly known as "industrial sapphire".

Extreme Hardness: Rated 9 on the Mohs hardness scale, second only to diamond, featuring excellent wear resistance and impact resistance.

High Temperature Resistance: Capable of long-term service at temperatures up to 1950°C with superior thermal stability.

Superior Corrosion Resistance: Resistant to strong acids, strong alkalis and plasma, with a service life 3 to 5 times that of quartz tubes.

Excellent Optical Performance: Transmittance spectrum covers ultraviolet, visible and mid-infrared bands (up to approximately 5.5μm).

High Mechanical Strength: Features good air tightness, high pressure resistance and excellent electrical insulation properties.

Semiconductor Industry: High-temperature/vacuum chambers and observation windows for etching and deposition equipment.

Optics and Laser Industry: Laser tube housings, UV lamp protective sleeves, and optical instrument components.

Chemical and Energy Industry: Heavy oil reactors, high-temperature and high-pressure fluid pipelines, and sensor sheaths.

Medical Instruments: Endoscopes, laser scalpels, and sterile fluid pipelines.

High-temperature Furnace Industry: Furnace tubes and observation windows for tube furnaces and muffle furnaces.
