XRD patterns of YA0 composition (Y0.62Al0.71B14) samples prepared by reactive SPS with AlF3 addition. The samples were sintered at 1773 K in a reduced Ar atmosphere for 1 h and 10 min under the uniaxial pressure of ~30 MPa, and for 5 min under the uniaxial pressure of 80 MPa, respectively. The standardized intensities for YxAlyB14 and YB6 are shown with sample’s XRD patterns.
