Structural ceramics mainly refer to a large class of new ceramic materials that exert their mechanical, thermal, chemical and other properties. They can serve in many harsh working environments, and thus become the key to the realization of many emerging science and technology.

Cubic boron nitride is a superhard material that is only 20 to 40 percent harder than diamond. Although second only to diamond in hardness, CNB surpasses gemstones in other important areas: The composite material does not react to carbon, making it possible to process steel, which accounts for 90 percent of mechanical engineering materials. By contrast, diamond reacts with one of its constituents, carbon, limiting its usefulness. Instruments made from nano-CNBs can cut metals that were previously uncut.

As a new ceramic material with excellent properties and great development potential, boron nitride includes five isomers: hexagonal boron nitride (H - BN), cubic boron nitride (C - BN), wurtzite boron nitride (W - BN), rhombic boron nitride (R - BN) and orthorhombic boron nitride (o - BN).
