Boron Nitride (BN) Blank

The 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-lubricating ceramic that can bear high temperatures 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.

Key Features

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 (>3000℃ 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 be used directly 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 2500℃, there’s a record for using our material at 3000℃+. Due to the low wettability with metals, boron nitride is an ideal material for metal melting works, especially for high-purity 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, and MBE systems
