Functions of Boron Nitride Crucible

• High Thermal Conductivity: Boron nitride has superb thermal conductivity, which means it can transfer warm efficiently. This residential property assists in the maintenance of an uniform temperature circulation within the crucible throughout the heating procedure.
• Chemical Inertness: BN is chemically inert to numerous compounds at high temperatures, making it resistant to rust or response with molten steels and salts.
• Reduced Coefficient of Thermal Development: Boron nitride shows a reduced coefficient of thermal development, which decreases the threat of splitting or damaging due to thermal shock when revealed to quick temperature changes.
• Electric Insulation: At area temperature and approximately very heats, boron nitride functions as an electrical insulator, which is essential for sure applications where electric conductivity could be bothersome.
• Lubricity: Boron nitride has a lubricating result even at high temperatures, which can be beneficial for certain production procedures.
