  • A new route is reported to prepare boron-rich rare-earth boride NdB6 under extreme of high pressure and high temperature conditions, i.e. oxidizing amorphous elemental boron with rare-earth oxide Nd2O3. Products are analyzed by X-ray powder diffraction. Results show that the pure phase of NdB6 is obtained under the condition of Nd∶B=1∶6, 4.0 GPa, 1 600 ℃ and 15 min. The method to prepare NdB6 under high pressure and high temperature has many advantages such as easy acquiring in reaction conditions, short reaction time and pure phase of the product ect. The results of XRD indicate that the crystallized product in cubic symmetry has lattice constant a=0.417 nm.
