Pyrolytic boron nitride (PBN) crucible is a specialized type of container or vessel used in high-temperature and ultra-high vacuum (UHV) applications, particularly in materials science, semiconductor manufacturing, and research laboratories.
Advantages:
– They can withstand high temperatures without warping or degrading.
– They are suitable for UHV applications.
– PBN crucibles offer exceptional purity and minimal contamination.
– Their chemical inertness makes them compatible with a wide range of materials and processes.
Uses of PBN Crucibles:
– Crystal Growth: They are used for the growth of single crystals and epitaxial layers of various materials, including semiconductors and superconductors.
– High-Temperature Furnaces: PBN crucibles are employed in high-temperature vacuum furnaces and thermal processing equipment.
– Semiconductor Manufacturing: PBN crucibles are commonly used in the production of high-purity semiconductor materials, such as gallium arsenide (GaAs) and silicon carbide (SiC).
– Materials Research: Researchers use PBN crucibles in experiments that require high-temperature environments and a controlled atmosphere, such as materials synthesis and characterization.
