    Abstract: A process for making a glass-ceramic article includes annealing an as-formed glass article formed from a glass-ceramic composition at a first temperature for a duration sufficient to nucleate a plurality of nuclei within a vitreous matrix of the as-formed glass article and forming a post-nucleation glass article. The process also includes annealing the post-nucleation glass article at a second temperature for a duration sufficient to grow crystalline grains within the vitreous matrix of the post-nucleation glass article and forming a glass-ceramic article. The first temperature is less than a glass transition temperature for the glass-ceramic composition and the second temperature is greater than the glass transition temperature for the glass-ceramic composition.

    IPC: C03C3/085

    Abstract: A glass-ceramic article that includes an article having a glass-ceramic composition, the composition including: SiO0 from about 45% to about 65%, Al2O3 from about 14% to about 28%, TiO2 from about 2% to about 4%, ZrO2 from about 3% to about 4.5%, MgO from about 4.5% to about 12%, and ZnO from about 0.1 to about 4% (by weight of oxide). The article can include a coefficient of thermal expansion (CTE) of about 20×10−7K−1 to about 160×10−7K−1, as measured over a temperature range from 25° C. to 300° C.

    Abstract: Embodiments of the present disclosure pertain to crystallizable glasses and glass-ceramics that exhibit a black color and are opaque. In one or more embodiments, the crystallizable glasses and glass-ceramics include a precursor glass composition that exhibits a liquidus viscosity of greater than about 20 kPa*s. The glass-ceramics exhibit less than about 20 wt % of one or more crystalline phases, which can include a plurality of crystallites in the Fe2O3—TiO2—MgO system and an area fraction of less than about 15%. Exemplary compositions used in the crystallizable glasses and glass-ceramics include, in mol %, SiO2 in the range from about 50 to about 76, Al2O3 in the range from about 4 to about 25, P2O5+B2O3 in the range from about 0 to about 14, R2O in the range from about 2 to about 20, one or more nucleating agents in the range from about 0 to about 5, and RO in the range from about 0 to about 20.
