Abstract
Boron carbide particles and whiskers, and titanium dioboride particles are demonstrated to be effective reinforcement materials to enhance the mechanical properties of a ceramic matrix. Various volume percents of titanium diboride particles, boron carbide particles, and boron carbide whiskers were dispersed in two different ceramic materials, ??alumina and the ceramic ionic conductor ???alumina. The critical parameters of volume fraction, size, and shape of the reinforcing additives are discussed. The simultaneous enhancement of both the fracture toughness and the modulus of rupture of ??alumina is shown.
