Abstract

Boron carbide powder was hot-pressed at 2070 degrees C with 30 MPa uniaxial pressure and 90 min soaking. The mechanical, microstructure and other related properties were evaluated. XRD of the boron carbide powder and sintered samples, shows the presence of B13C2 phase of high electrical conductivity. Crystal lattice parameters, space group, cell angle, cell parameters, etc. were found from Rietveld refinement. The micro Vicker's hardness was 26.98 +/- 0.98 GPa at 4.9 N load, fracture toughness 3.54 +/- 0.26 MPa/Mt and Young's modulus 461.50 +/- 4.5 GPa. The hot-pressed boron carbide was found to be electrically conducting, which can be machined using a wire electrical discharge machine (WEDM).
