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.

5 FAQs of Insulating Pyrolytic Boron Nitride Wafer Pbn Ceramic Plate

Insulating Pyrolytic Boron Nitride (PBN) ceramic plates are advanced materials used in high-temperature and vacuum environments. Here are five common questions about these products.

What is a PBN ceramic plate? PBN ceramic plates are made by depositing boron nitride gas onto a substrate under high heat. This process creates a material with high thermal stability and electrical insulation. It is ideal for applications requiring resistance to extreme temperatures and chemical corrosion.

Where are PBN plates typically used? These plates are common in semiconductor manufacturing, especially in processes like molecular beam epitaxy (MBE) or chemical vapor deposition (CVD). They also serve in high-purity environments such as laboratories or aerospace components. Their ability to withstand rapid temperature changes makes them suitable for precision equipment.

How high a temperature can PBN ceramic plates handle? PBN plates operate reliably in temperatures up to 1800°C in vacuum or inert gas settings. In oxygen-rich environments, their limit drops to around 800°C due to oxidation risks. This makes them better for controlled atmospheres compared to standard ceramics.

What advantages do PBN plates have over other ceramics? PBN offers lower thermal expansion and higher thermal conductivity than materials like alumina or quartz. It resists reaction with most metals and acids, ensuring minimal contamination. Its layered structure provides excellent electrical insulation, even under stress. These traits improve process consistency in sensitive applications.

Are there special handling requirements for PBN plates? PBN is brittle. Avoid mechanical shock or sudden temperature shifts. Clean surfaces with non-abrasive methods like alcohol wipes. Store in dry conditions to prevent moisture absorption. Proper handling extends lifespan and maintains performance.
