Boron Nitride Blank, BN Blank
Boron Nitride Blank is a type of high-performance ceramic material that is made from boron nitride powder through a high-temperature and high-pressure sintering process. Boron Nitride Blank has exceptional thermal stability, excellent electrical insulation, and high mechanical strength, making it an ideal material for a wide range of industrial applications.
Boron Nitride Blank is known for its high thermal conductivity and low thermal expansion, making it a useful material in high-temperature applications such as crucibles, nozzles, and heat sinks. Its exceptional electrical insulation properties make it a popular choice for electronic components and high-voltage insulators.
Boron Nitride Blank is also highly resistant to chemicals and oxidation, making it an ideal material for use in harsh environments. It has a low coefficient of friction, making it useful in applications where lubrication is not possible or desirable.
Boron Nitride Blank is available in a range of shapes and sizes, including blocks, plates, tubes, and custom shapes. Its properties make it a versatile material that is used in industries such as aerospace, semiconductor manufacturing, metallurgy, and automotive manufacturing.

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 usually the raw material to make the other machined parts. It could also directly be applied directly as insulators in some electronic or vacuum equipment with simple machining. Boron Nitride Blank Applications Boron Nitride Blanks Applications
High purity BN could withstand higher temperatures in a vacuum than lower purity enhanced BN products. Although we usually claim the maximum working temperature as 2500C, there’s a record to use 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 metal in a vacuum.
Boron nitride ceramic from CG Material can withstand high temperature in a high vacuum environment, plus it has excellent corrosion resistance and electrical resistance. Thus, 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
