In the aerospace field, the selection of materials directly affects the performance, safety, and reliability of aircraft. As a professional manufacturer that has been deeply involved in the field of quartz products for many years, we provide customized quartz plate solutions for global aerospace customers based on our deep understanding of quartz material characteristics and technological innovation.

The core characteristic of quartz plates is that they are designed for extreme environments

Quartz plate (made from high-purity silica as raw material and processed by special technology) has the following key characteristics, making it a "must-have material" in the aerospace field:

Excellent high temperature resistance

Quartz plates can withstand high temperatures above 1200 ℃ for a long time and extreme environments of 1600 ℃ for a short period of time, with an extremely low coefficient of thermal expansion (only 1/10 of ordinary glass). This characteristic makes it the core material for spacecraft reentry insulation tiles, such as the rigid ceramic composite insulation tile covering the belly of a certain type of space shuttle. Its core component is quartz fiber-reinforced quartz based composite material, which can withstand high temperature impacts of 1650 ℃.

Excellent transparency and electromagnetic compatibility

The quartz plate has a transmittance of over 95% for light in the ultraviolet to near-infrared wavelength range (185-3500nm), and also has extremely low dielectric loss (tan δ<1 × 10 ⁻⁴). This characteristic makes it the preferred material for radar covers, satellite antenna windows, and interference electromagnetic emission windows. For example, the optical window of the sun sensor of a certain model of high orbit satellite adopts our company's radiation resistant quartz plate, which can effectively cut off ultraviolet radiation and has a service life of over 10 years in orbit.

Outstanding chemical stability and radiation resistance

Quartz plates have strong corrosion resistance to acids, bases, salts, and organic solvents, and are not prone to producing "color centers" (photo induced defects) under cosmic ray irradiation, ensuring long-term stable optical performance. This feature makes it a key component of the optical system of deep space probes. For example, in a Mars exploration mission, the high-precision quartz crystal oscillator carried by the probe was packaged in our customized quartz plate, ensuring the precise operation of the navigation and communication system.

Typical application scenarios in the aerospace field

The application of quartz plates in the aerospace field has covered the entire lifecycle of aircraft design, manufacturing, and operation

Thermal protection system

Space shuttle insulation tile: a ceramic based composite insulation tile reinforced with quartz fiber, which protects the spacecraft structure from high temperature erosion during reentry by low thermal conductivity (<0.1W/m · K) and high melting point characteristics.

Engine nozzle and exhaust tube: The inner lining of a certain model of rocket engine nozzle is made of our company's quartz plate, which can withstand high-temperature gas erosion above 3000 ℃ while maintaining structural integrity.

Optics and Transparency Systems

Satellite optical window: The optical window of high orbit satellites' sun sensors, Earth observation cameras, and other equipment must simultaneously meet the requirements of UV transparency, radiation resistance, and lightweight. Our company has customized a UV grade quartz plate for an international satellite project, with a thickness of only 2mm and a transmittance of 99.2%.

Airborne/missile radar cover: A radar cover made of a composite of quartz plate and prepreg, which can withstand aerodynamic heating and vibration impact during high-speed flight while ensuring wave transmittance (>90%). The radar cover of a certain stealth fighter jet is made of our company's quartz plate substrate, achieving a balance between radar wave stealth and structural strength.

Semiconductor and Electronic Systems

Aerospace grade chip manufacturing: In the space environment, chips need to withstand radiation and extreme temperature fluctuations. The quartz plate carrier provided by our company for an international space station project is used to carry high-purity silicon wafers, ensuring that they are not contaminated during high-temperature processes such as diffusion and oxidation.

High precision quartz crystal oscillator: As the "heart" of navigation and communication systems, the frequency stability of quartz crystal oscillators directly determines the success or failure of tasks. The SC Cut quartz crystal oscillator packaging board customized by our company for a deep space exploration mission has an annual frequency deviation of<1 × 10 ⁻⁹, which helps the detector to accurately locate.

Choose our four core advantages

Customization capability for the entire industry chain

We have built a complete production system from high-purity quartz sand purification (purity ≥ 99.998%) to precision processing of quartz plates (tolerance ± 0.01mm). For example, an international aerospace client needs to customize a batch of ultra-thin quartz plates (thickness 0.5mm), and our company achieves mass production with a yield rate of over 99.5% through plasma melting technology and CNC polishing process.

Technical certification and standard guidance

Our company has obtained ISO 9001 quality management system certification, and our products comply with international standards such as SEMI and NASA. For example, our quartz plate has been certified by the Semiconductor Equipment and Materials Institute (SEMI) and has participated in the development of multiple industry standards for quartz products used in aerospace.

Quick response and differentiated services

In response to the high customization requirements of aerospace projects, our company provides a "72 hour rapid sampling" service and is equipped with a professional engineering team to optimize design solutions. For example, a certain European satellite project requires urgent replacement of optical window materials. Our company completed material selection and sample delivery within 48 hours to assist the project in launching on time.

Global supply chain and localization support

We have established warehousing and technical support centers in Europe and North America, which can achieve "localized production+global distribution". For example, a North American aerospace client shortened the delivery cycle of quartz plates from 6 weeks to 72 hours through our regional warehouse, significantly reducing logistics costs.

Customer Case: From Laboratory to Starry Ocean

Case 1: An international satellite project

The customer needs to customize radiation resistant quartz plates for high orbit satellite sun sensors, with a requirement of a service life of ≥ 15 years in orbit. Our company has significantly improved the radiation resistance of quartz plates by optimizing the doping process (adding 0.5% CeO ₂), and the final product has passed NASA standard testing, helping our customer's satellite successfully enter orbit.

Case 2: Radar Cover of a Certain Type of Stealth Fighter Aircraft

The customer needs to balance the transmittance and structural strength of the radar cover. Our company adopts a mixed weaving process of quartz fiber and carbon fiber to develop lightweight (density 1.8g/cm ⊃3;) and high-strength (bending strength>500MPa) composite quartz plates, which help customers achieve breakthroughs in stealth performance for their fighter jets.
