Descripción de producto

Cutting Edge Sapphire Tube EFG KY Method Optical Grade Al2O3 Crystal

 

Product Introduction

Sapphire tube is made of sapphire and sapphire is a single crystal of Al₂O₃ (aluminum oxide), featuring high hardness (Mohs 9), excellent high

temperature and chemical corrosion resistance, good electrical insulation, and optical transparency. It is well-suited for demanding applications involving high temperatures, high pressures, corrosive environments, and stringent insulation requirements. Typical forms include: sapphire capillaries/micro-conduits used for protecting high-temperature measurements, sapphire optical conduits/optical rods serving as infrared windows or light paths, and sapphire tube materials/probes designed for extreme environments.

 

 

Product Highlights:

 

Extremely High Biocompatibility: Sapphire tube has stable chemical properties. It does not react chemically with human tissues or blood, nor does it release harmful substances, meeting the biosafety standards for medical implants.

Superior Hardness and Wear Resistance: With a Mohs hardness of 9, second only to diamond, sapphire tube can resist friction and extrusion when inserted into human blood vessels or organs. It is not prone to scratches or deformation, ensuring the structural stability of the catheter.

Excellent High-Temperature Resistance and Chemical Stability: Sapphire tube can withstand high-temperature sterilization (e.g., autoclave sterilization) and resist corrosion from chemical disinfectants such as strong acids and alkalis. It maintains stable performance even after repeated use.

Good Optical Transmittance: Some sapphire tubes can leverage their optical properties and work with devices like endoscopes and lasers .

Q&A:

 

Q: What is a sapphire tube ?

 

A: A sapphire tube is a cylindrical component made from synthetic sapphire (single-crystal aluminum oxide, Al₂O₃), known for its exceptional hardness, high optical clarity, and resistance to heat and chemicals.

 

Q: What are sapphire protection tubes ?

 

A: Sapphire protection tubes are cylindrical protective components made of sapphire material. They are mainly used to shield internal sensitive parts (such as sensors, heating elements, or optical fibers) from damage in harsh environments, while ensuring the normal operation of the protected parts (e.g., signal transmission, heat conduction).

 

Q: What is a sapphire capillary tube?

 

A: A sapphire capillary tube is an ultra-thin, hollow cylindrical component made of sapphire (α-Al₂O₃), typically with an inner diameter ranging from a few micrometers to hundreds of micrometers. It combines sapphire’s inherent material advantages with the structural characteristics of capillary tubes, making it ideal for scenarios requiring precise fluid delivery, micro-sensing, or optical signal transmission in harsh environments.
