In the cutting-edge field of aerospace, the selection of materials directly affects the performance, safety, and reliability of aircraft. Quartz rod, as a high-performance special material, is increasingly becoming an indispensable key component in this field.

Key Applications of Quartz Rod in Aerospace

Quartz rod (usually refers to high-purity fused silica or synthetic quartz material) is widely used in the following key scenarios due to its unique physical and chemical properties:

-Optical and sensing systems: used as optical windows, lens supports, and transparent materials for inertial navigation systems, star sensors, and lidar to ensure high-precision signal transmission.

-Thermal management and protection: As a high-temperature observation window and insulation support material, it is used for engine monitoring and thermal protection around the combustion chamber.

-Electrical insulation and support: As an insulation bracket and antenna cover lining for electronic equipment in high temperature and high frequency environments, it ensures the stability of communication systems.

-Special process equipment: used in high-end manufacturing processes such as semiconductor process equipment (such as spacecraft chip manufacturing) and vacuum sintering brackets.

The core advantages and solutions of quartz rods

1. Extreme temperature stability

-Advantages: Extremely low coefficient of thermal expansion (about 5.5 × 10 ⁻⁷/℃), strong heat shock resistance, and a working range of -180 ℃ to 1200 ℃.

-Problem solving: Avoid deformation or rupture caused by drastic temperature changes, and ensure dimensional stability in extreme environments such as high altitude and re-entry into the atmosphere.

2. Excellent optical and dielectric properties

-Advantages: Wide transmission band (UV to IR), low dielectric constant (about 3.8), small loss tangent, excellent insulation performance at high frequencies.

-Problem solving: Improve the imaging quality of optical systems, reduce signal attenuation, and ensure the reliability of radar and communication equipment in complex electromagnetic environments.

3. High purity and chemical inertness

-Advantages: SiO ₂ content ≥ 99.99%, acid resistant (except hydrofluoric acid), plasma resistant, and extremely low gas release rate.

-Problem solving: Prevent material contamination of sensitive environments (such as vacuum systems and clean chambers), extend component lifespan, and be suitable for space vacuum environments.

4. Mechanical strength and lightweight

-Advantages: High bending strength, low density (about 2.2 g/cm ⊃3;), superior to most metals and ceramics.

-Problem solving: Achieve structural weight reduction to meet the lightweight requirements of aerospace, while maintaining sufficient support strength.
