More info

Boron nitride blank consists of high-purity BN ceramics. Boron Nitride, also known as BN, Hexagonal boron nitride (H-BN), and hot-pressed boron nitride, is a good self-lubricate ceramic that can bear high temperature and maintain its lubricating capability in a high vacuum environment. Hexagonal boron nitride (H-BN) behaves similarly to graphite mechanically but offers excellent electrical resistance.

Boron Nitride Blank Advantages

  • Low wettability to molten metal
  • 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)

Boron Nitride Blank Applications

Boron nitride (BN) blanks are often the raw material to make the other machined parts. It could also directly be used as an insulator in some electronic or vacuum equipment with simple machining. 

High-purity BN could bear higher temperatures in a vacuum than lower-purity-enhanced BN products. Although It's known that the maximum working temperature is 2500C, there’s a record for using our material at 3000+ C. Due to the low wettability with metals, boron nitride is an ideal material for metal melting works, especially for high-purity material metals in a vacuum.

Boron nitride ceramic from Heeger Materials can withstand high temperatures in a high vacuum environment. Besides, 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:

  • Crucibles for crystal growth
  • Evaporator Boats
  • Break rings for horizontal casting machine
  • Components for PVD, MOCVD, MBE system
