Boron Nitride Ceramics: The Understated “king Of Materials”

In the field of materials science, diamond is a household name for its unrivaled hardness, and graphite is widely used for its electrical conductivity and lubricity. However, little known is that they also have a "close relative" - boron nitride ceramics, which is not as widely known as diamonds and graphite, but in many high-tech fields play an indispensable role, can be called a low-key "The king of materials".

Boron nitride (BN) is a crystal composed of nitrogen and boron atoms, with carbon atoms composed of diamond and graphite structure is similar. Depending on the arrangement of the atoms, boron nitride is divided into two main structures:

Hexagonal Boron Nitride (h-BN): Similar in structure to graphite, it is arranged in layers and has a soft texture, and is known as "white graphite". It has excellent lubricity, high temperature resistance, chemical stability and electrical insulation.

Cubic boron nitride (c-BN): structure similar to diamond, is known to be second only to the hardness of diamond substances, but also has a high thermal conductivity, chemical inertia and other advantages.

Guardian" in the field of high temperature: boron nitride ceramics are resistant to high temperature and oxidation, and can withstand high temperatures of more than 2,000 degrees Celsius, which is an ideal material for the manufacture of high-temperature furnaces, rocket nozzles and other high-temperature equipment.

Good helper" in the electronic industry: boron nitride ceramics have excellent insulating properties and good thermal conductivity, and are high-quality materials for manufacturing high-frequency circuit boards and semiconductor heat sinks.

Mechanical processing of the "tool": cubic boron nitride high hardness, good wear resistance, can be made into cutting tools, abrasives, used for processing hardened steel, cold hard cast iron and other difficult to process materials.

Lubrication field of the "best": hexagonal boron nitride interlayer bonding force is weak, easy to slide, is an excellent solid lubricant, can be used for high temperature, high pressure and other harsh environments lubrication.

Other fields: boron nitride ceramics can also be used in the manufacture of wave-transparent materials, nuclear reactor shielding materials, biomedical materials.
