  • Heat treatment for strengthening glasses
    Patent number: 9751802
    Abstract: A method of making a strengthened glass article. The method includes altering the glass structure and subsequently creating a compressive layer extending from the surface of the glass to a depth of layer. In some embodiments, the structure is altered by heat treating the glass at a temperature that is less than the annealing point of the glass, and the compressive layer is formed by ion exchange. A strengthened glass article made by the method is also provided.

The first surface of the glass body may be etched to a depth less than or equal to about 25% of the maximum initial flaw depth Ai of the flaw population present in the first surface. When the glass article is under uniaxial compressive loading, at least a portion of the first surface is in tension and a uniaxial compressive strength of the glass article is greater than or equal to 90% of a uniaxial compressive strength of a flaw-free glass article.

  • Ion exchangeable glass with advantaged stress profile
    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.
