Quartz Boat FAQ

1. What are the typical applications of quartz boats?

Quartz boats are commonly used in semiconductor wafer diffusion, oxidation, annealing, and other thermal treatment processes. They are also used in photovoltaic manufacturing, laboratory furnaces, and specialized industrial equipment that requires heat-resistant material carriers.

2. Can quartz boats withstand high temperatures?

Yes. Quartz boats are suitable for many high-temperature applications because quartz glass has a high softening temperature and a low coefficient of thermal expansion. However, the maximum recommended operating temperature depends on the quartz grade, load, heating duration, atmosphere, and thermal cycling conditions.

3. Are quartz boats resistant to chemicals?

Quartz glass offers good resistance to many acids and process chemicals. However, it is vulnerable to hydrofluoric acid (HF), hot concentrated phosphoric acid under certain conditions, and strong alkaline environments, particularly at elevated temperatures. Chemical compatibility should be evaluated before use.
