Hot Pressed Boron Nitride is an excellent electrical insulator and does not require humidity to act as a lubricant. BN has poor mechanical properties, however, it generally has very high temperature heat capacity, excellent thermal conductivity, outstanding dielectric strength and easy machinability. In reducing and inert atmospheres, BN can withstand temperatures in excess of 2,000°C. BN comes in a variety of different grades in solid and powder form, all with slightly differing properties.
Boron nitride has high heat capacity, outstanding thermal conductivity, easy machinability, lubricity, low dielectric constant and superior dielectric strength.
