The Difference Between Hexagonal Boron Nitride And Graphite

Hexagonal boron nitride is very similar to graphite, similar structure, has similar parameters, high-temperature resistance, and roller skating, what is the difference between these two substances?

Graphite is made of the same elements as carbon but arranged in a different way. An opaque gray-black solid with a density of 2.25, excellent corrosion resistance, and a melting point of up to 3,600 degrees Celsius. Stable chemical properties, and acid and alkali agents are not easy to react. Oxygen burns to form carbon dioxide but can be oxidized by strong oxidants, potassium permanganate, concentrated nitric acid, etc. Its function is to be used as an antiwear agent, can be used as a lubricant, commonly used as the material of electronic products and pencil lead etc.

Hexagonal boron nitride is also known as white stone ink, white powder appearance, because the nitrogen and boron in hexagonal boron nitride also form hexagonal mesh layer, overlapping each other, forming crystals, crystals and graphite similar, parameters are similar. Hexagonal boron nitride has good thermal conductivity, very high-temperature resistance, insulation, and lubrication, often used as a high-temperature lubricant, can also be used as PA, PE, and other polymers additives; Additives of various thermal interface materials, enhance thermal conductivity, as cosmetic additives,  mild and have pearlescent effect.
