    Abstract
  • BN is synthesized by benzene thermal method using (C2H5)2OBF3 and Li3N as reactants and its phase transition mechanism is studied. Not only hBN and cBN are found in the products testified by XRD and FTIR, but also oBN, atmosphere form Li3BN2(O) and high pressure form Li3BN2(T) are discovered. The differences of cBN catalytic mechanism between high pressure and high temperature method and benzene thermal synthesis method are analyzed. Furthermore, the catalytic mechanism of Li3BN2 to synthesize BN using Li3N and (C2H5)2OBF3 as reactants is discussed. At the same time, it stands out the atmosphere form Li3BN2(O) and the high pressure form Li3BN2(T) can catalyze the synthesis of cBN and oBN, respectively.
