ZrB2 and HfB2 were prepared by metallothermic reduction (MTR) of ZrO2, ZrSiO4, and HfO2 with Mg or Mg and MgO mixtures. We understood that the theory of function-building fine particle preparation was able to be applied to synthesize nano-atomized fine particles of ZrB2. ZrB2 can also be obtained directly from mixture of ZrSiO4, B2O3, and Mg by MTR method. This sample has no borides such as silicon boride except for ZrB2. Therefore, this result shows the possibility to obtain ZrB2 easily from natural source. In addition, HfB2 can also be synthesized by MTR method using HfO2 which was calcined over 750°C.
