Sapphire tube small size K9 high hardness pipe transparent unpolished military industry research

Short Description:

Sapphire tubes made of synthetic sapphire have a unique combination of excellent optical, physical and chemical properties. Sapphire is one of the hardest minerals, with a Mohs hardness of 9 and almost scratch resistance. Sapphire has a melting point of up to 2030 °C. Its excellent thermal conductivity and heat resistance make it ideal for high temperature applications. Its excellent chemical stability and corrosion resistance can withstand harsh environments such as fluorine, plasma, acid and alkaline. In addition, sapphire provides an excellent transmission bandwidth of 0.15-5.5μm between UV and IR. The edge-defined film feeding method (EFG method) enables the production of sapphire tubes of various shapes with minimal or no grinding. All of these unique properties provide a cost-effective solution for applications that require the hardness, scratch resistance, corrosion resistance, heat resistance and optical properties of sapphire tubes.

The following are the characteristics of sapphire tube

Sapphire tube is a tubular material made of high purity sapphire（Al2O3）, with excellent physical and chemical characteristics, such as high temperature resistance, high pressure resistance, wear resistance and so on.

1. High transparency: Sapphire tube has excellent light transmission in the visible and near infrared range, suitable for optical applications.

2. Excellent heat resistance: The high melting point of sapphire enables it to work stably in high temperature environments and is widely used in high temperature equipment.

3. Extremely high hardness: sapphire Mohs hardness of 9, with strong scratch resistance, suitable for wear need occasions.

4. Good electrical insulation: sapphire is an excellent insulating material, suitable for electronic and electrical equipment.

5. Low thermal expansion coefficient: Its low thermal expansion characteristics make sapphire maintain shape stability when the temperature changes, suitable for precision instruments.

6. Chemical stability: Sapphire has good tolerance to most chemicals and is suitable for harsh environments.

7.High mechanical strength: sapphire tube has high compressive strength and bending strength, and can withstand greater physical pressure.

The following is the widely used way of sapphire tube

1. Laser: Used for laser tubes or optical components.

2. Medical equipment: such as endoscopes and laser treatment equipment.

3. Optical window: Used for various optical instruments and sensors.

4. Durable consumer goods: such as high-end watch mirrors and electronic equipment protection covers.
