Abstract: Methods of forming a glass-ceramic article, the method are provided. Embodiments of the method may include initially nucleating a precursor glass composition at a first nucleation temperature and maintaining the first nucleation temperature for a pre-nucleating time period to produce a pre-nucleated crystallizable glass composition, wherein the pre-nucleated crystallizable glass composition comprises 5 wt % to 20 wt % crystalline phase ASTM C1365-18, forming the pre-nucleated crystallizable glass composition into an initial 3D shape; further nucleating the initial 3D shape for a nucleating time period to a second nucleation temperature to produce a nucleated crystallizable glass composition; and ceramming the nucleated crystallizable glass composition to a crystallization temperature and maintaining the ceramming temperature for a crystallization time period to produce the glass-ceramic article. The glass-ceramic article may have a final 3D shape is within 0.1 mm of the original design specifications.

Abstract: Methods of processing glass-based substrates to reduce birefringent defects and glass-based substrates are disclosed. In one embodiment, a method for processing a glass-based substrate includes rolling a glass-based material to form the glass-based substrate, and heat treating the glass-based substrate by increasing a temperate of the glass-based substrate, holding the temperature at a maximum temperature for a hold period, and then decreasing the temperature at one or more cooling rates, wherein after the heat treating, the glass-based substrate has a retardance over thickness of 5 nm/mm or less at locations outside of and including 5 mm from any corner of the glass-based substrate and outside of and including 5 mm from any edge of the glass-based substrate.

Abstract: A method for determining crystal phases of a glass ceramic sample, including the steps of applying energy to the sample using an excitation source, detecting raw Raman spectral energy that is given off by the sample using a detector, wherein the raw Raman spectral energy includes peak values, determining a plurality of predetermined energy peaks based off a composition of the sample, superimposing the plurality of predetermined energy peaks over the raw Raman spectral energy, applying a baseline value between each predetermined energy peak, subtracting the baseline value from the raw Raman spectral energy, calculating corrected peak values based on the raw Raman spectral energy and baseline value, and determining the crystal phases of the glass ceramic sample based on the corrected peak values.
