Product Description
High Purity Electrically-Insulating Boron Nitride BN Ceramic Parts Components
Boron Nitride (BN) ceramic parts are advanced components known for extreme high-temperature stability (up to 2000°C), excellent electrical insulation, and superior thermal shock resistance. Because they are easily machinable, they are frequently custom-manufactured into insulators, crucibles, nozzles, and thermal management fixtures for semiconductor manufacturing and metallurgy.
Key Physical & Thermal Properties:
Boron Nitride—specifically the hexagonal (h-BN) form—offers a unique combination of characteristics that make it ideal for demanding engineering applications:
● Thermal Stability:
Retains its structural integrity up to 2000°C in vacuum or inert atmospheres. In air, it is typically limited to around 900°C.
● Thermal Conductivity & Shock:
Dissipates heat effectively while possessing a very low thermal expansion coefficient, preventing cracking under rapid temperature cycling.
● Electrical Insulation:
Maintains high dielectric strength and electrical resistivity even at elevated temperatures.
● Chemical Inertness & Non-Wetting:
Highly resistant to chemical attacks and will not react with or adhere to most molten metals (like aluminum, magnesium, and zinc).
● Machinability:
Has a low Mohs hardness (around 2) and a layered, self-lubricating crystal structure, allowing it to be easily machined into highly complex, custom shapes using standard tooling.
| Properties of Boron Nitride (BN) | ||
| Property | Typical Value | Notes |
| Thermal Conductivity | Up to 400 W/m·K | Higher than Alumina/Zirconia |
| Electrical Resistivity | >10¹³ Ω·cm | Excellent insulation |
| Density | ~2.1 g/cm³ | Lightweight ceramic |
| Maximum Use Temperature | ~900 °C (air), >2000 °C (inert) | Depends on environment |
| Coefficient of Thermal Expansion | ~1–2 ×10⁻⁶ /K | Very low |
| Chemical Resistance | Excellent | Resistant to most molten metals |
Common Applications:
Because of these properties, BN ceramic parts are frequently utilized in highly specialized industrial fields:
◆ Semiconductor Processing:
Used for high-temperature insulators, wafer handling fixtures, and parts used in crystal growth.
◆ Metallurgy:
Fabricated into crucibles, break rings in continuous casting, and nozzles for molten metal handling.
◆ Welding & Plasma:
Provides durable, heat-resistant, and electrically isolating components for plasma arc welding equipment.
