Hexagonal Boron Nitride, also known as "white graphite", has a similar crystal structure to graphite. Compared with graphite, hexagonal boron nitride has more superior properties, its crystal structure has good lubricating properties, and the appearance exists in the form of white powder.
Hexagonal boron nitride
Hexagonal boron nitride characteristics highlights:
Low coefficient of friction: Low coefficient of friction of only 0.5 to 0.7 for excellent lubricating properties.
Chemical stability: It has good chemical inertness and is not easy to react with other substances.
Electrical insulation: As an electrical insulator, it can effectively prevent the flow of electric charges.
Thermal conductivity: Excellent thermal conductor for more efficient heat dissipation.
High temperature stability: It has excellent temperature resistance in different environments, with a melting point of nearly 3000 °C, so it shows excellent characteristics in high temperature environments.
Low thermal expansion: It has characteristics such as low thermal expansion and low dielectric constant.
Chemical Attack Resistance: It has a strong resistance to chemical attack and is not easily wetted by glass and most metals.
Ease of processing: It is easy to process in the hot pressing state and can process complex shapes.
