Source: English Wikipedia. (PhysOrg.com) — Currently, diamond is regarded to be the hardest known material in the world. But by considering large compressive pressures under indenters, scientists have calculated that a material called wurtzite boron nitride (w-BN) has a greater indentation strength than diamond.12 Feb 2009.

Fearing his potential power, Homeworld officials exiled him, and he became known as The Renegade. The first, wurtzite boron nitride has a similar structure to diamond, but is made up of different atoms. The second, the mineral lonsdaleite, or hexagonal diamond is made from carbon atoms just Wurtzite Boron Nitride has a hardness which even exceeds diamond and can usually only be produced via shock compression methods, such as detonation, or static compression at high pressures. The high hardness of w-BN material makes it suitable for use in the following applications: Wurtzite Boron Nitride has a hardness which even exceeds diamond and can usually only be produced via shock compression methods, such as detonation, or static compression at high pressures.

Wurtzite Boron Nitride – a material harder than diamond. Like many materials, Boron Nitride is available in more than one crystal form. Each form of the material offers distinctly different properties. The two commonly known crystal forms of Boron Nitride are: Hexagonal Boron Nitride (h-BN): Easily machined. Offers lubricating properties.

The density of the wurtzite type boron nitride was proved to be smaller by about 1 % than that of zinc blende type boron nitride synthesized under static compression. References (16) M. Wakatsuki et al.

19 Jan 2016 The synthetic material boron nitride, first produced in 1957, is similar to carbon in that it has several allotropes. In its cubic form (c-BN) it shares 

Both c-BN and w-BN are formed by compressing h-BN, but formation of w-BN occurs at much lower temperatures close to 1700 °C. Graphite-like boron nitride was shock-compressed up to 550 kbar. The X-ray diffraction pattern of the recovered specimen identified the wurtzite structure whose hexagonal cell dimensions were a 0 = 2.553±0.003 A ̊, c 0 = 4.228±0.004 A ̊.
