Abstract
ZrO2-toughened glass-ceramic has high molar fractions of tetragonal ZrO2 and may also include also contain other secondary phases, including lithium silicates, that may be beneficial for toughening or for strengthening through an ion-exchange. Additional secondary phases may also decrease the coefficient of thermal expansion of the glass-ceramic. A method of making such glass-ceramic is also provided.
