Boron Nitride(BN), Hexagonal boron nitride (H-BN), and hot-pressed boron nitride are good self-lubricate ceramics that can withstand high temperatures and maintain their lubricating capability in a high vacuum environment. HM's Boron Nitride rods are made from hot-pressed boron nitride blank. Hexagonal boron nitride (H-BN) behaves similarly to graphite mechanically but provides amazing electrical resistance. Hexagonal boron nitride rods are particularly useful when the electrical conductivity of graphite would be a problem.

Boron Nitride Rod Advantages

BN rods are easily machinable, and they are of high performance:

• Low wettability to molten metal
• Low dielectric constant
• Relatively high dielectric strength
• Relatively high thermal conductivity with low thermal expansion
• Relatively high thermal shock resistance
• Extremely high working temperature with proper inert gas protection (>3000C has been recorded).
• Chemical Vapor Deposition (CVD)

Boron Nitride Rod Applications

Boron Nitride ceramic from Heeger Materials can withstand high temperatures in a high vacuum environment, plus it is chemically inert — it has excellent corrosion resistance and electrical resistance. Therefore, Boron Nitride ceramic product is an ideal choice in a wide range of industries, such as:

• Evaporator Boats
• Nozzles for the nonferrous metals metallurgy industry
• Electric insulators in the vacuum environment
• Insulators for high-temperature furnace
• Spacers for glass melting
