Abstract: ZrO2-toughened glass ceramics having high molar fractions of tetragonal ZrO2 and fracture toughness value of greater than 1.8 MPa·m1/2. The glass ceramic may also include also contain other secondary phases, including lithium silicates, that may be beneficial for toughening or for strengthening through an ion exchange process. Additional second phases may also decrease the coefficient of thermal expansion of the glass ceramic. A method of making such glass ceramics is also provided.

Abstract: Locally cerammed optically transparent glass-ceramic articles for consumer products. The locally cerammed glass-ceramic articles may have one or more primary glass-ceramic regions including primary crystal phases of a glass-ceramic material and one or more secondary glass-ceramic regions including secondary crystal phases of the glass-ceramic material. The primary glass-ceramic region(s) may be optically transparent and the secondary glass-ceramic region(s) may be non-optically transparent. The primary glass-ceramic region(s) may have a fracture toughness less than the fracture toughness of the secondary glass-ceramic region(s).
