PBN crucibles have several advantages:
1. Thermal Conductivity: PBN has excellent thermal conductivity, which allows for even heating of the materials contained within the crucible.
2. High Temperature Resistance: PBN can withstand extremely high temperatures, often over 2000°C, making it ideal for processes that require such conditions.
3. Low Outgassing: PBN has low outgassing properties, which is important in applications like vacuum deposition processes.
4. Cleanroom Compatibility: PBN materials are often used in cleanroom environments due to their low particulate generation.
5. Inert Material: PBN is chemically inert and does not react with most chemicals or materials, making it suitable for use with a wide range of substances.
PBN crucibles are commonly used in semiconductor manufacturing, as they can hold and transport high-purity materials without contaminating the process. They are also used in research settings where high-temperature and chemically stable containers are needed.
