Boron Nitride (BN) Rod

New product

Hexagonal BN is a composite of boron and nitrogen that is both heat and chemically resistant. It is the most robust crystalline type of boron nitride, along with graphite. Boron Nitride Rod has excellent electrical insulation, excellent chemical stability, and excellent dielectric properties. Heeger Materials (HM) has over two decades of experience in the manufacture and sale of the BN Rod.

More info

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
