Abstract
An armor component including a body having a first portion including calcium boride compounds include non-stoichiometric calcium boride (CaBx) and stoichiometric calcium boride (CaB6) 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 (CaB6). In another aspect, the first portion can further include a third phase comprising boron carbide (B4C).

An armor component comprising:
- a body including:
- a first portion including at least about 90 wt % calcium boride compounds and having a density of at least about 80% theoretical density, wherein the calcium boride compounds include non-stoichiometric calcium boride (CaBx) and stoichiometric calcium boride (CaB6).
An armor component comprising:
- a body including:
- a first portion including:
- a first phase comprising silicon carbide (SiC), wherein the first phase has an average grain size (GS1) of not greater than about 6 microns;
- a second phase comprising calcium boride (CaB6), wherein the second phase has an average grain size (GS2) of not greater than GS1;
- and
- a density of at least about 80% theoretical density.
