ЧАСТО ЗАДАВАЕМЫЕ ВОПРОСЫ
1. Q: Can fused quartz glass windows be used in high-temperature applications?
A: Yes. Fused quartz windows can operate continuously up to ~1100°C and withstand short-term exposures up to 1250°C. Their extremely low thermal expansion coefficient (0.55 × 10⁻⁶ /°C) ensures dimensional stability under rapid temperature changes, making them ideal for furnaces, laser systems, and semiconductor equipment.
2. Q: Are custom shapes and sizes available for fused quartz plates?
A: Absolutely. We offer round, square, elliptical, slotted, and fully custom geometries according to CAD drawings. Machining tolerances can reach ±0.01 mm, and surface flatness up to λ/10 ensures compatibility with high-precision optical systems.
3. Q: How resistant are fused quartz windows to chemicals and UV/IR radiation?
A: Fused quartz glass is chemically inert to most acids, alkalis (excluding HF), and organic solvents. It also maintains high transmission from UV (200 nm) to IR (~3500 nm) wavelengths, making it suitable for laser optics, sterilization lamps, and analytical instruments in harsh chemical and radiation environments.
