Frequently Asked Questions (FAQ)

Q: What is the specific transmittance of this UV quartz plate in the ultraviolet spectrum? A: Our high-transmittance transparent quartz plates offer excellent transmission performance in the deep ultraviolet and ultraviolet bands. In the ultraviolet spectral region, transmittance can reach over 80%, while transmittance in the visible light region exceeds 93%. Depending on the application, we also offer materials of different grades, such as JGS1 (far-ultraviolet grade) and JGS2 (ultraviolet grade).

Q: What are the maximum custom sizes for round and square quartz plates? A: We have proven capabilities for processing large-size components. Round plates can be custom-made up to a maximum diameter of 500 mm, while square plates can reach dimensions of up to 700 mm × 700 mm. Thickness can be flexibly adjusted within the range of 1–100 mm based on requirements. Specific specifications can be precisely cut and polished according to drawings.

Q: Will these quartz plates shatter when used in high-temperature environments? A: No. These quartz plates have an extremely low coefficient of thermal expansion—1/10 to 1/20 that of ordinary glass—and exhibit excellent thermal stability. Tests have shown that even when heated to 1,100°C and then immediately placed in room-temperature water, they will not shatter, allowing them to withstand various environments with extreme temperature fluctuations with ease.

Q: Aside from high light transmittance, how does this product perform in terms of chemical resistance? A: Quartz plates are acidic materials with extremely high chemical stability. With the exception of hydrofluoric acid, they react with almost no acidic substances. Their acid resistance is 30 times that of ceramics and 150 times that of stainless steel, enabling them to effectively withstand erosion in corrosive environments.

5-800mm spacecraft thermal control system quartz plate

The 5-800mm spacecraft thermal control system quartz plate is a high-performance optical element specially designed for spacecraft thermal management. It is made of high-purity fused silica material and has excellent thermal stability, high transmittance and low thermal expansion coefficient. This product can be widely used in the thermal control system of satellites, space stations, deep space probes and other spacecraft, effectively regulating the temperature distribution inside and outside the spacecraft, ensuring the stable operation of equipment in extreme space environments.

FAQ: Frequently Asked Questions About Quartz Plates for Spacecraft Thermal Control Q1: Why is quartz used in spacecraft thermal control systems instead of ordinary optical glass? Spacecraft thermal control systems are exposed to extreme temperature fluctuations, high-energy radiation, and the risk of collisions with space debris. Quartz has a coefficient of thermal expansion of only 5.5×10⁻⁷/°C—approximately one-twentieth that of ordinary glass—and can withstand transient temperature differences of several hundred degrees Celsius without developing thermal stress cracks. Additionally, quartz offers high transmittance across a broad spectral range from ultraviolet to infrared, allowing it to serve as an optical sensor window that supports both temperature measurement and imaging functions. Under the same conditions, ordinary optical glass is highly susceptible to thermal shock fracture and cannot meet the requirements for reusable spacecraft.

Q2: How should one choose among the three grades—JGS1, JGS2, and JGS3? JGS1 (Ultraviolet Fused Quartz): With a hydroxyl content of approximately 2,000 ppm, excellent transmittance in the 185–2,500 nm wavelength range, with transmittance reaching 90% at 185 nm; suitable for deep-ultraviolet detection system windows and high-precision optical components. JGS2 (Optical Fused Quartz): Hydroxyl content of 100–200 ppm, transmittance range of 200–2,500 nm, offering a balanced cost-performance ratio; suitable for conventional thermal control windows and sensor protective covers. JGS3 (Full-Spectrum Fused Quartz): Virtually free of hydroxyl groups, with a transmission range of 260–3,500 nm and infrared transmittance exceeding 85%, making it suitable for windows in infrared thermal imaging systems and high-temperature radiation shields.

Q3: What exactly does the “custom size range of 5–800 mm” refer to? 5–800 mm refers to the outer diameter or side length range of the quartz plates. Small sizes (5–50 mm) are used for sensor windows and fiber optic connector protection; medium sizes (50–300 mm) are used for equipment viewing windows and thermal control heat sinks; large sizes (300–800 mm) are used for thermal insulation covers on large enclosures or array-type heat dissipation assemblies. We can customize circular, square, or irregular shapes based on customer design drawings, with thicknesses ranging from as thin as 0.5 mm to over 50 mm.

Will Drilling Holes in Quartz Slabs Cause Cracks

Whether quartz plates crack during drilling depends primarily on the machining process, equipment precision, and the physical properties of the material itself. As a highly hard and brittle material, using standard drill bits or applying excessive force during drilling can easily lead to chipping or cracking due to thermal stress concentration. However, by selecting industrial-grade diamond drill bits, implementing continuous water cooling, and allowing for scientifically calculated safety margins, it is entirely possible to achieve high-precision, damage-free drilling that ensures the structural stability of the finished product.

From the user’s perspective, we fully understand that in precision manufacturing and engineering applications, the machining quality of quartz slabs directly determines the yield rate and service life of the final product. We are committed to providing you with a one-stop solution—from drawings to finished products—to thoroughly resolve challenges such as machining cracks, excessive dimensional tolerances, and performance degradation under extreme conditions. Through customized secondary processing services, we help clients eliminate cumbersome secondary processing steps, significantly reducing material waste and production time costs, and ensuring that every quartz plate perfectly meets your core application requirements.
