Boron carbide (B4C) is a significant advanced ceramic material with its high melting point, exceptional hardness and low density. It is an appropriate material for different usage areas such as defense industry and nuclear applications. Although it has various superior properties, low fracture toughness is a main disadvantage for the B4C based materials. Thus, different additives are used to improve its fracture toughness. Carbon Nanotube (CNT) and Graphene Nanoplatelet (GNP) are widely used as additive materials to improve mechanical properties of ceramic materials. In this study, B4C based composites are prepared with the additions of 3 vol% CNT and 0-3 vol% GNP by spark plasma sintering (SPS) method. Samples are produced at different sintering temperatures under 40 MPa for 5 min. The effects of CNT and GNP additions on densification behavior, microstructure and mechanical properties of B4C were investigated.
