Synthesis of YB 2 C 2 by high‐energy ball milling and reactive spark plasma sintering
Abstract X‐ray pure yttrium diborodicarbide (YB 2 C 2 ) was synthesized for the first time via modified spark plasma sintering (SPS) using Y 2 O 3 , B 4 C, and carbon as starting materials. Homogeneous intermixing of the raw powder by high energy ball milling (HEBM) promoted the formation of YB 2 C...

powder with layered structure by boro/carbo‐thermal reduction. The average particle size of the synthesized powder at an optimum synthesis temperature (1625℃) was 568 nm. Small amount of YB

C was formed by consuming YB

at and above 1625°C. The metal basis purity of the synthesized YB

powder was 99.84%. X‐ray pure YB

was obtained by densifying the synthesized YB

powder at 1900°C for 60 minutes at a pressure of 80 MPa using SPS. This study reports a simple method for the fabrication of X‐ray pure rare earth metal diborodicarbides (ReB
