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.

5 FAQs of Hot Press Boron Nitride Ceramic Sheet Pyrolytic Boron Nitride PBN Plate / Substrate / Wafer

What is Hot Press Boron Nitride Ceramic Sheet?
Hot Press Boron Nitride (PBN) Ceramic Sheet is a high-performance material made by compressing boron nitride powder under high heat. It has strong thermal stability, electrical insulation, and chemical resistance. It works well in extreme temperatures and harsh environments.

What are the main uses of PBN plates?
PBN plates are used in high-temperature furnaces, semiconductor manufacturing, and laser equipment. They handle molten metals, act as crucibles, or serve as substrates for electronic components. They are common in aerospace, electronics, and research labs due to their reliability under stress.

Why choose PBN over other ceramics?
PBN offers better thermal conductivity than alumina or quartz. It resists most acids and alkalis. It does not react with molten metals or semiconductors. Its low thermal expansion reduces cracking risks during temperature changes. These traits make it last longer in tough conditions.

How to handle and store PBN products?
PBN is brittle. Avoid dropping or applying sudden force. Clean surfaces with alcohol or mild solvents. Do not use abrasive materials. Store in dry areas away from moisture. Keep it separate from materials that might scratch or damage it.

Can PBN sheets be customized?
Yes. Sizes, thicknesses, and surface finishes can be adjusted. Some suppliers offer coatings or machining for specific shapes. Check with manufacturers for technical limits. Custom orders may take longer due to production requirements.
