Zirconia Stabilized Boron Nitride Properties

Zirconia Stabilized Boron Nitride (ZSBN) is a composite material that leverages the unique advantages of both boron nitride and zirconia, resulting in a set of enhanced properties suitable for high-performance and high-temperature applications. Here are the key properties of ZSBN:

• Enhanced Mechanical Strength: The inclusion of zirconia significantly improves the mechanical strength and toughness of boron nitride, making ZSBN more resistant to mechanical shock and wear.
• High Thermal Conductivity: ZSBN maintains the excellent thermal conductivity characteristic of boron nitride, facilitating effective heat dissipation, which is critical in applications requiring efficient thermal management.
• Superior Thermal Shock Resistance: The composite material exhibits exceptional resistance to thermal shock, a benefit attributed to the thermal stability of zirconia. This property is essential for materials used in environments experiencing rapid temperature changes.
• Chemical Inertness: ZSBN retains the chemical inertness of boron nitride, offering resistance to attack from most chemicals and molten metals. This makes it suitable for use in chemically aggressive environments.
• Excellent Electrical Insulation: Like boron nitride, ZSBN provides outstanding electrical insulation properties. This feature, combined with its thermal management capabilities, makes it highly suitable for electronic applications where electrical insulation is a critical factor.
• Low Thermal Expansion: The material exhibits low thermal expansion, similar to boron nitride, which minimizes dimensional changes and mechanical stress in response to temperature fluctuations.
• Good Metallization Compatibility: ZSBN can be effectively combined with metals through metallization processes, enhancing its utility in electronic packaging and device fabrication.

These properties make Zirconia Stabilized Boron Nitride a versatile material choice for a wide range of applications, including electronics, aerospace, industrial processing, and wherever high temperature, wear resistance, and thermal management are required.
