Generally,pressure(＞11-12 Gpa)and temperature(～2000 ℃)are required to achieve the formation of wurtzite and cubic boron nitride(wBN and cBN)from hexagonal boron nitride(hBN).For preparing sp3-bonded boron nitride[1](wBN,cBN)under moderate conditions,here we developed a solvothemal hot-press method,by which the phase transformation in boron nitride(BN)nanoparticles was realized at quite low temperature(250～310℃)and pressure(60～150MPa).
