  • Patent number: 9714192
    Abstract: Ion exchangeable glass compositions that develop concentration profiles and stress profiles that have higher magnitudes of concentration and compressive stress profiles than those provided by the error function (erfc)-shaped compressive stress profile for similar surface concentrations of stress-inducing components such as K+ or K2O and stresses. The advantaged stress profile is the result of a glass composition that is low in K2O (or potassium) in the base glass prior to ion exchange. A glass comprising lower amounts of K+ or K2O has a stronger dependence of diffusivity on concentration, leading to a non-erfc-shaped concentration profile. Several glass compositions that contain low amounts of K+ or K2O exhibit this beneficial effect, whereas other glasses containing higher amounts of K+ or K2O do not exhibit this effect.

  • Patent number: 9365446
    Abstract: Methods for processing glass using select wavelength radiation in a convective environment, broadly referred to as “Local Temporary Annealing”, “LASER Edge Strengthening” and “LASER Enhanced Thermal Strengthening.” Local Temporary Annealing allows strengthened glass to be brought to a neutral stress state so daughter units can be cut from strengthened glass and other processes usually only performed on annealed glass. LASER Edge Strengthening allows surface compression to be thermally imparted to the edges of a whole sheet or daughter units cut from annealed glass, or modification of residual edge stress profiles in strengthened glass to produce stable, strengthened edges. LASER Enhanced Thermal Strengthening allows surface compression to be imparted to a sheet of annealed glass whilst maintaining reduced surface temperatures so the glass has superior geometric stability and surface compression can be imparted at levels not conventionally possible.
