Abstract: Methods for regenerating poisoned salt bath comprising providing a salt bath comprising at least one of KNO3 and NaNO3, providing an ion-exchangeable substrate comprising lithium cations, contacting at least a portion of the ion-exchangeable substrate with the salt bath, whereby lithium cations in the salt bath diffuse from the ion-exchangeable substrate and are dissolved in the salt bath, and selectively precipitating dissolved lithium cations from the salt bath using phosphate salt. The methods further include preventing or reducing the formation of surface defects in the ion-exchangeable substrate by preventing or reducing the formation of crystals on the surface of the ion-exchangeable substrate upon removal from the salt bath.

Abstract: Glass and glass ceramic compositions having at least a lithium disilicate crystalline phase, a petalite crystalline phase, and a residual glass phase along with methods of making the glass and glass ceramic compositions are described. The compositions are compatible with conventional rolling and float processes, are transparent or translucent, and have high mechanical strength and fracture resistance. Additionally, processes of 3D forming glass ceramic preforms having the glass ceramic composition discussed to produce glass ceramic articles are described. Further, the compositions are able to be chemically tempered to even higher strength glass ceramics that are useful as large substrates in multiple applications.

Abstract: Glass-based articles are provided with improved stress profiles. The glass-based articles provide improved drop performance and damage resistance. The glass-based articles may be produced with a single ion exchange treatment. Methods of manufacturing a glass-based article includes exposing a glass-based substrate to a single molten salt bath to form the glass-based article. The glass-based substrate contains lithium. The single molten salt bath includes potassium nitrate (KNO3) and potassium carbonate (K2CO3) that is dissolved in the single molten salt bath. A concentration of the K2CO3 remains at or below its solubility limit in the single molten salt bath. A concentration of lithium ions in the single molten salt bath remains at or below its solubility limit in the single molten salt bath.
