Frequently Asked Questions About Quartz Tubes

1. Are quartz tubes suitable for semiconductor manufacturing?

Yes. High-purity quartz tubes are widely used in semiconductor processing equipment, including diffusion furnaces, oxidation systems, annealing equipment, and other high-temperature wafer processing applications. Their low contamination potential and thermal stability help support consistent manufacturing conditions.

2. What is the difference between quartz tubes and ordinary glass tubes?

Quartz tubes generally offer much higher temperature resistance, lower thermal expansion, and better thermal shock resistance than ordinary soda-lime glass tubes. They can also provide superior performance in demanding high-purity and optical applications. Ordinary glass may be more economical for applications that do not require these specialized properties.

3. Are quartz tubes resistant to chemical corrosion?

Quartz tubes exhibit excellent resistance to many acids and chemical reagents. However, they are vulnerable to hydrofluoric acid and can be attacked by strong alkaline solutions, particularly at elevated temperatures. Chemical compatibility should always be evaluated according to the specific medium, concentration, and operating temperature.
