FAQ—Frequently Asked Questions

Q: What are the key advantages of this quartz tube under operating conditions of 1100°C? A: Its key advantages lie in its extremely low hydroxyl content (controllable to below 10 ppm) and highly dense glassy structure. This allows it to maintain an extremely low crystallization rate even during prolonged exposure to high temperatures, effectively preventing tube embrittlement, cracking, and reduced light transmittance caused by crystallization, resulting in a service life far exceeding that of ordinary quartz tubing.

Q: What key dimensional parameters can be customized for this product? A: We offer highly flexible customization services. The outer diameter ranges from 1.5 mm to 300 mm and even larger diameters; wall thickness can be adjusted as needed within the range of 0.5 mm to 30 mm; and lengths can be customized to non-standard specifications ranging from 10 mm to over 3,000 mm. We can accommodate everything from micro-reaction tubes to large furnace tubes.

Q: How chemically stable is this quartz tube in different process atmospheres? A: Except for hydrofluoric acid and hot phosphoric acid above 300°C, this material is chemically inert to the vast majority of acids, halogens, and neutral salts. In high-temperature processes such as diffusion and oxidation, it effectively blocks the migration of impurity ions, ensuring the cleanliness of the process chamber.

Crafted from high-purity synthetic quartz, it features exceptional spectral transmittance, an extremely low coefficient of thermal expansion, and outstanding chemical stability. Quartz plates in this thickness range offer excellent mechanical strength and flatness while ensuring high light transmittance, making them indispensable core components for precision optical systems.

FAQ Q1: What are the fundamental differences between JGS1 transparent UV quartz plates and JGS2 and JGS3? A: JGS1 is a far-ultraviolet optical quartz glass manufactured from synthetic quartz. It features extremely high transmittance and no absorption bands in the 185–2500 nm wavelength range, making it particularly suitable for short-wavelength ultraviolet applications. JGS2 is primarily used in the 220–2500 nm wavelength range, while JGS3 is geared toward infrared applications in the 260–3500 nm range. Q2: What are the optical advantages of quartz plates with a thickness of 5–10 mm? A: 5–10 mm is a commonly used thickness for precision optical windows and laser protection. This specification maintains extremely high transmittance from the ultraviolet to the near-infrared (with transmittance in the visible light region reaching over 93%) while providing excellent surface flatness (e.g., λ/10) and extremely low parallelism deviation, effectively reducing optical path difference and wavefront distortion. Q3: Can your company provide custom sizes and specialized coating services? A: Absolutely. We offer custom machining for outer diameters ranging from 1 mm to over 600 mm, with thickness tolerances controlled within ±0.05 mm.
