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.
