Abstract
The effect of an isothermal heat-treatment on the strength and fracture surface energy of a glass-ceramic derived from a lithium silicate glass has been studied. It is found that the strength and effective surface energy for crack initiation increase as the mean free path in the intercrystalline glass decreases. The strengthening and toughening mechanisms are discussed.
