An armor component including a body having a first portion including calcium boride compounds include non-stoichiometric calcium boride (CaB x ) and stoichiometric calcium boride (CaB 6 ) and having a density of at least about 80% theoretical density. In one aspect, the first portion can include a first phase comprising silicon carbide (SiC) and a second phase comprising calcium boride (CaB 6 ). In another aspect, the first portion can further include a third phase comprising boron carbide (B4C). |
