Abstract
An integrally formed high density ceramic pellet, for use in a ballistic armor plate, has a longitudinally extending body portion and an impact receiving end face. The impact receiving end face includes an impact receiving proximal segment that is convexly curved and a distal segment that merges with a top surface of the body portion. The distal segment has lateral surfaces that have a region including at least a portion which is concave in configuration or a region including a substantially smooth angled configuration. A cross-sectional area of the distal segment at the area of merger is greater than a cross-sectional area taken across a nominally designated base of the proximal segment. The length of the contour line of the outer surface of the distal segment is between 5 and 25% of that of the entire integrally formed impact receiving end face.
