Overview of Boron Nitride Ceramic

Boron Nitride (BN) ceramic is a unique material renowned for its exceptional properties, making it highly valuable in various industrial applications. It exists in multiple forms, primarily hexagonal boron nitride (h-BN), cubic boron nitride (c-BN), and wurtzite boron nitride (w-BN). Hexagonal BN, the most common form, is often compared to graphite due to its lubricious and thermally conductive yet electrically insulating nature. Boron Nitride ceramics are synthesized under high temperatures and pressures, offering a rare combination of properties not found in many other materials.

Features of Boron Nitride Ceramic

Thermal Conductivity: Excellent thermal conductivity, especially in the hexagonal form, allowing efficient heat dissipation.

Electrical Insulation: Outstanding electrical insulation properties make it ideal for electrical applications requiring thermal management.

Chemical Stability: Highly resistant to chemical attacks, including strong acids and bases, ensuring durability in harsh environments.

Thermal Shock Resistance: Superior resistance to thermal shock, enabling it to withstand rapid temperature changes without cracking.

Mechanical Strength: Good mechanical strength at both room and elevated temperatures, although this can vary with the form of BN.

Lubricity: Self-lubricating property due to its layered structure, which reduces friction and wear in moving parts.

Non-Toxic: Safe to use in various settings, including medical and food processing industries, due to its non-toxic nature.

High-Temperature Performance: Maintains stability at extremely high temperatures, exceeding 1000°C in inert atmospheres, making it suitable for refractory applications.

Specification of insulating machinable ceramics boron nitride ceramic block BN product

Boron nitride ceramic blocks are high-performance products made for requiring industrial applications. These blocks combine thermal stability, electric insulation, and mechanical workability. The product deals with severe temperature levels well. It remains steady in air as much as 850 ° C and in inert settings as much as 2000 ° C. This makes it suitable for high-temperature processes like heater parts or semiconductor manufacturing.

The thermal conductivity of boron nitride ceramic blocks is high. It ranges in between 15-30 W/m · K. This building allows effective warm dissipation. Unlike metals, boron nitride is electrically shielding. It stands up to malfunction voltages up to 40 kV/mm. This twin ability suits applications requiring both thermal monitoring and electric seclusion.

Machinability establishes boron nitride besides various other ceramics. It can be reduced, drilled, or formed making use of standard carbide tools. This decreases production time and costs. The material maintains dimensional stability throughout machining. It does not split or chip easily. Completed parts have smooth surface areas and tight resistances.

Chemical resistance is one more essential attribute. Boron nitride resists molten metals, salts, and acids. It does not respond with a lot of corrosive substances. This makes it suitable for crucibles, ladles, or safety cellular linings in harsh settings. The product also has low wettability. Liquified products like light weight aluminum or glass do not stay with its surface.

Thickness varieties from 1.8 to 2.1 g/cm FOUR. This light-weight building reduces load on supporting structures. Mechanical toughness remains modest. Flexural toughness is around 30-60 MPa. While not as solid as alumina or zirconia, boron nitride compensates with thermal and electrical performance.

Applications extend aerospace, electronics, metallurgy, and energy industries. Common uses consist of insulators, heat sinks, diffusion sources, and plasma arc components. The material works well in vacuum systems. It outgasses minimally under high temperatures.

Boron nitride ceramic blocks are readily available in typical dimensions. Custom-made dimensions can be created based upon needs. Material purity typically surpasses 99%. Qualities differ based upon thickness, porosity, and additive content. Customers should select grades aligned with specific operational needs.
