BN (Boron Nitride) Crucible
- High Thermal Conductivity: Boron nitride exhibits excellent thermal conductivity, which helps in evenly distributing heat within the crucible, ensuring uniform melting and preventing hot spots in high-temperature applications.
- High-Temperature Resistance: BN crucibles can withstand temperatures up to 3000°C in an inert atmosphere, making them ideal for high-temperature processes like metal melting, sintering, and crystal growth.
- Chemical Inertness: BN crucibles are highly resistant to chemical corrosion, including resistance to molten metals, acids, and alkalis, making them ideal for use in aggressive chemical environments.
- Low Thermal Expansion: Boron nitride has a low coefficient of thermal expansion, which minimizes the risk of cracking and warping under thermal stress and temperature fluctuations.
- Electrical Insulation: BN possesses excellent electrical insulation properties, which can be beneficial in applications where electrical conductivity must be minimized.
- Non-Toxic and Environmentally Friendly: Unlike some other high-performance materials, boron nitride is non-toxic and environmentally safe, making it a preferred choice for many industries.
