Abstract :
B13C2 boron carbide ceramic was prepared by pulsed electric current sintering from raw element boron and graphite powders. The planar defects in (1 0 4) planes were investigated by transmission electron microscopy and X-ray photoelectron spectroscopy. The results showed the B12 C–B–C configuration of B13C2 ceramic agreed well with C1s spectra measurement. The weakly linked C–B–C chains made the atomic disorder in (1 0 4) planes which led to defects in these planes.
