Abstract
Ceramic articles having improved fracture toughness are prepared by ion bombardment of ceramic particles by gas ions to impregnate the particles, cold compacting the gas ion-containing ceramic particles into a form, and hot pressing the gas ion-containing ceramic particle form into a ceramic article whereby gas bubbles are formed in and substantially homogeneously dispersed throughout the ceramic article.
