Custom Polished Transparent Sapphire Tubes Wear-Resistant High-Hardness
A sapphire polished tube is a hollow tubular component manufactured through precision processing of high-purity synthetic sapphire (single-crystal aluminum oxide, α-Al₂O₃). It exhibits exceptional hardness, thermal stability, and chemical inertness. As a customizable product, its diameter, length, and surface treatment (e.g., polishing, coating) can be flexibly adjusted according to specific application requirements. For instance, the diameter range can reach 3–460 mm, and the length can be customized up to several meters. ZMSH provide end-to-end services from material growth to finished product processing, supporting the customized production of various sapphire components including substrates, wafers, tubes, and rods, ensuring high performance and long service life in extreme environments.
Exceptional Mechanical Properties: Mohs hardness up to level 9 (second only to diamond), excellent compressive strength, and wear resistance. It can withstand high pressure and mechanical impact, extending service life.
Outstanding Thermal and Chemical Stability: Withstands high temperatures up to 1800°C, has a low coefficient of thermal expansion, and resists corrosion from strong acids and alkalis (except hydrofluoric acid), making it suitable for high-temperature or corrosive environments.
High Optical Transmittance and Low Loss: High transmittance in the ultraviolet to infrared wavelength range (e.g., 0.15–5 μm), with optical loss as low as 0.1–0.3 dB/cm, suitable for optical signal transmission and laser applications.
Size Flexibility and Customization: Wide customizable diameter range (e.g., 3–460 mm). Wall thickness, length, and surface roughness (e.g., mirror polishing to Ra ≤ 0.005 μm) can be adjusted as needed to meet the integration requirements of precision instruments.
Fiber Optic Communications and Laser Devices: Used as fiber optic interfaces, optical transmission tubes for lasers, or coupling components to ensure high-precision optical signal transmission.
Semiconductors and Precision Instruments: Employed in semiconductor manufacturing equipment such as plasma introduction tubes, vacuum viewports, and sensor protection sleeves. It withstands plasma erosion while maintaining transmittance.
High-Temperature Industrial Equipment: Used as thermocouple protection tubes or reactor viewports in chemical, metallurgical, or glass industries, enduring high temperatures, high pressure, and chemical corrosion.
Medical and Scientific Research Equipment: Applicable for endoscopes, laser medical devices, or laboratory instrument windows, combining biocompatibility with high cleanliness.
