Boron Nitride, hexagonal boron nitride (HBN), and hot-pressed boron nitride are good self-lubricate ceramics that will withstand high temperatures and maintain their lubricating capability during a high vacuum environment. Hexagonal boron nitride (HBN) behaves similarly to graphite mechanically but offers excellent electrical resistance. The Boron Nitride Plates and Boron Nitride Sheets from Heeger Materials are made from hot-pressed boron nitride blank.

Boron Nitride Plate Advantages

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

Boron Nitride Plate Applications

Boron Nitride ceramic from Heeger Materials can withstand heat during a high vacuum environment, plus it's chemically inert — excellent corrosion resistance and electric resistance. Thus, Boron Nitride ceramic product is a perfect choice in a wide selection of industries, such as:

• Electric insulators in vacuum system
• Insulators for high-temperature furnace
• Spacers for glass melting
• Boron Nitride parts for ion injection equipment
