Aqueous tape casting of boron carbide ceramic ScienceDirect

1. Introduction. It is widely acknowledged that boron carbide ceramics are formed with strong covalent C–B and B–B bonds which gives them some superior properties, such as extremely high hardness (Vickers: 3770 kg/ mm 2), good erosion behavior, high wear resistance and melting point, plus with low density (2.52 g/ cm 3) and high neutron absorption cross section,,,, .
