What is claimed is: 1. A component comprising: a unitary, single piece, monolithic, sintered boron carbide body consisting essentially of boron carbide and graphite and comprising entirely of ceramic, said unitary, single piece, monolithic, sintered boron carbide body having an exterior surface, a center region which includes boron carbide, and a region that includes boron carbide surrounding and adjacent said center region and extending continuously from said center region to said exterior surface, wherein the concentration of graphite in said region surrounding and adjacent said center region is less than the concentration of graphite of said center region, and wherein said region surrounding and adjacent said center region is essentially free of graphite. 2. The component of claim 1, wherein said boron carbide body is a part of an armor arrangement. 3. The component of claim 1, wherein said boron carbide body is a part of a personal armor arrangement. 4. The component of claim 3, wherein said personal armor arrangement is a helmet. 5. The component of claim 3, wherein said personal armor arrangement is shaped to the contours of a part of a human body. 6. The component of claim 3, wherein said part of said human body is head, or torso, or back, or groin, or arm, or leg, or shoulder, or hip. 7. The component of claim 3, wherein said contour corresponds to either a male body or a female body. 8. The component of claim 1, wherein said boron carbide body is a part of a vehicular armor arrangement. 9. The component of claim 1, wherein graphite content of said region surrounding said center region is less than 0.05% by mole. 10. The component of claim 9, wherein said region surrounding said center region is at least 25 microns thick. 11. The component of claim 1, wherein said region surrounding said center region is at least 25 microns thick.
