Quartz Glass & Quartz Glass Tubes FAQ – Engineering, Manufacturing & Procurement Guide
🟢 PART 1 — Basic Knowledge FAQ (8 Questions)
1. What is quartz glass?Quartz glass, also known as fused silica glass, is composed of nearly pure SiO₂. It features outstanding heat resistance, chemical inertness and excellent optical performance, widely used in high-temperature, optical, semiconductor and laboratory fields.
2. What is a quartz glass tube?
A quartz glass tube is tubular fused silica component. As a core industrial part, it is widely applied in heating furnaces, UV systems, lab instruments and semiconductor production lines.
3. What are the main types of quartz glass?
It is categorized into transparent quartz glass, opaque quartz glass, natural fused silica and low-OH synthetic quartz glass based on raw materials and production processes.
4. What are common quartz glass products?
Main products include quartz glass tubes, quartz rods, quartz plates, quartz windows, quartz crucibles and other customized quartz components.
5. What industries use quartz glass tubes most?
Semiconductor, optical engineering, laboratory research, UV disinfection, industrial heating and photoelectric equipment are the major application industries.
6. What is UV grade quartz glass?
UV grade quartz glass has low hydroxyl content and ultra-high transmittance in ultraviolet spectrum, specially designed for UV lamps, spectroscopy and precision optical systems.
7. What is IR grade quartz glass?
IR grade quartz glass maintains stable light transmission in infrared band, perfect for infrared heating equipment and thermal detection devices.
8. What is the difference between quartz glass and ordinary glass?
Quartz glass is made of high-purity silicon dioxide, while ordinary glass contains multiple additives. Quartz glass has far better high-temperature resistance, lower thermal expansion, superior optical performance and chemical stability.
🟡 PART 2 — Engineering & Material FAQ (12 Questions)
9. What is the purity of your quartz glass?
Standard grade ≥99.99%; semiconductor and optical grade reaches 99.999%, with strictly controlled impurities and OH content.
10. What temperature can quartz glass withstand?
It can work continuously at up to 1100°C, and resist short-term instant temperature up to 1200°C, with excellent thermal shock resistance.
11. Why is quartz glass resistant to high temperature?
It owns an ultra-low thermal expansion coefficient, so it rarely cracks under drastic temperature changes.
12. Is quartz glass chemically resistant?
It resists most strong acids, alkalis and corrosive substances. Only hydrofluoric acid and hot strong alkali can cause corrosion.
13. What is the optical transmittance of quartz glass?
It delivers high transmittance across UV, visible and near-infrared range. UV grade performs excellently within 200–300nm ultraviolet band.
