The present invention contemplates the addition of zirconium compounds to well known ceramic ballistic materials to increase resistance to penetration by projectiles. In the preferred embodiments of the present invention, the zirconium compound that is employed consists of ZrO2 and is provided in the range of about 0.1% to about 11%, by weight, of starting material before densification. Preferred ranges of proportion of ZrO2 in the finished ceramic material are in the ranges of about 0.30% to about 0.75%, by weight, or about 8-9%, by weight.
