We measured their longitudinal-wave elastic constants CL between 20 and 300 K using picosecond ultrasound spectroscopy. Their room-temperature values are 945 ± 3 GPa and 930 ± 18 GPa for cBN and wBN, respectively. The shear modulus G of cBN was also determined by combining resonance ultrasound spectroscopy and micromechanics calculation as G Wurtzite boron nitride is a metastable superhard material that is a high-pressure polymorph of BN. Clarifying how the metastable high pressure material can be stabilized at atmospheric pressure is a challenging issue of fundamental scientific importance. Here, we fabricate millimeter-size w-BN bulk crystals via the hexagonal-to-wurtzite phase transformation at high pressure and temperatures. By combining transmission electron microscopy and ab initio molecular dynamics simulations, we reveal a s Micro-grains of wurtzite boron nitride(wBN) crystal have been observed in 5.0-7.0 GPa pressure and 1800-2000 K temperature where cubic boron nitride has been synthesized in a catalyst. The wBN grain size is about 20-30 nm. The presence of these micro grains indicates that the pressure for wBN growth could be lower than that found in the previous work. The first, wurtzite boron nitride, is similar to diamond but comprises different atoms. The second, the mineral lonsdaleite, is made from carbon a Wurtzite Boron Nitride (wBN) is a wide band gap BN polymorph with unique mechanical properties such as hardness and stiffness.

Our first-principles study investigates the electronic, vibrational, and optical properties of wBN across a broad range of pressures. We account for the electron-hole interaction

Super Abrasive Wurtzite Boron Nitride

It's a relatively new super abrasive material used in conjunction with detonation. Wurtzite BN is the next step in the evolution of boron nitride, after the well-known cubic BN and another substance called graphite, which has a structure similar to hexagonal BN.
