<p>This invention provides a ceramic pellet for use in a ballistic armor plate, the ceramic pellet comprising a body portion, comprising an axis, a cross-sectional shape that is symmetrical around the axis and an end portion representing a terminus of said body portion. The end portion has an outer surface comprising a first and second section (1-40,1-50), wherein the first section (1-40) has a convex curvature, the first section is spaced from the body portion, and the first section contains a body portion axis extending there-through; and the second section (1-50) extends around the body portion axis, with the second section being located between the first portion and body portion; and the second section having a first annular edge (1-60) at or adjacent to the first section (1-40) and second annular edge at or adjacent to said body portion. The second section (1-50) has a configuration such that substantially each intersection between the second section (1-50) and planes including a body portion axis extends in a straight line or a configuration such that substantially each intersection between the second section (1-50) and planes including the body portion axis extends in a line that has a concave curvature when viewed from the exterior of said pellet. The pellet further comprises an end portion, wherein an average radial distance from said body portion axis to said first annular edge of the second section (1-50) is at lest 5 % less than an average radial distance from the body portion axis to the second annular edge of the second section (1-50). Composite armor comprising the ceramic pellets and methods of producing the ceramic pellets are disclosed, as well.
