▎ 摘　　要

Simultaneous synthesis and densification of boron carbide and boron carbide-graphene nano platelets (GNP) were carried out by reactive spark plasma sintering of amorphous boron and graphene nano platelets at temperature ranging from 1200 to 1600 degrees C, pressure of 50 MPa and heating rate of 50 degrees C/min and 100 degrees C/min. X-ray diffraction and Raman spectroscopy confirmed the formation of required phases. Electron microscopic images revealed the formation of sub-micron and nano sized grains of plate like morphology. Sintered product with high relative density of 96%TD was achieved at a temperature of 1600 degrees C and heating rate of 50 degrees C/min for B4C stoichiometric composition and also exhibited maximum hardness of 21.10 GPa.
