Abstract: Carbon monolith and carbon-nano silicon carbide composites are developed at a heat treatment temperature of 1400°C in inert atmosphere using coal tar pitch derived green coke as such and green coke mixed with 5, 10 and 15% of nano silicon carbide powder respectively. The nano silicon carbide used is derived by the reaction between silicon and carbon black at temperature of 1400°C. The density, flexural strength and scleroscopic hardness of the carbon-nano silicon carbide composites are found to be higher as compared to the carbon monolith. The bending strength and scleroscopic hardness increased up to 29.2% and 22.2% respectively.
