The aerospace industry has extremely strict performance requirements for materials, which require high temperature resistance, thermal shock resistance, high purity, and chemical stability. Quartz tubes have become one of the indispensable key materials in this field due to their unique physical and chemical properties.  

The core application of quartz tubes in aerospace

1. Testing of spacecraft thermal protection system

-Application scenario: Quartz tubes are used to simulate high-temperature environments and test the extreme temperature resistance of spacecraft insulation materials (such as ceramic based composite materials).  

-Product requirement: High purity quartz tube (SiO ₂ ≥ 99.99%), long-term temperature tolerance ≥ 1200 ℃.  

2. Rocket engine observation window and sensor protective cover

-Application scenario: As a combustion chamber observation window or sensor protective cover, quartz tubes need to maintain transparency and structural integrity in high-pressure and high-temperature gas environments.  

-Product requirements: low bubble density, high thermal shock resistance (Δ T ≥ 1000 ℃).  

3. Satellite optical systems and communication equipment

-Application scenario: Quartz tubes are used as UV optical lenses, laser carriers, or antenna protection covers, requiring low thermal expansion coefficient (5.5 × 10 ⁻⁷/℃) and high UV transmittance (≥ 90%).  

4. Aerospace grade electronic component packaging

-Application scenario: High purity quartz tubes are used to package precision sensors, oscillators, and other components inside spacecraft to prevent space radiation and particle erosion.  

Advantages and Solutions of Quartz Tube

1. Extreme environmental stability

-Resistant to high temperatures of over 1200 ℃ and instant thermal shock with a temperature difference of up to 1000 ℃, avoiding rupture caused by sudden temperature changes.  

-Problem solving: Thermal shock during the ignition phase of rocket engines and damage to materials caused by extreme temperature differences in space.  

2. High purity and chemical inertness

-SiO ₂ content ≥ 99.99%, no heavy metal precipitation, no reaction with fuel or oxidant.  

-Problem solving: Prevent contamination of spacecraft propulsion systems and ensure accuracy of sensor data.  

3. Excellent optical performance

-High transmittance in the ultraviolet to infrared band, with a transmittance fluctuation range of less than 0.5% (wavelength 190nm-2500nm).  

-Problem solving: Ensure the signal transmission accuracy of satellite remote sensing and navigation systems.
