Abstract: The invention relates to glass articles, in particular flat glasses, in the case of which the surface material has gradient material properties as a result of targeted process control which in turn lead to compressive prestressing of the surface. The invention also relates to a method for producing the glass articles and the use thereof.

Abstract: A thermally tempered glass element is provided made of glass with two opposite faces that are under compressive stress of at least 40 MPa. The glass has a working point at which the glass has a viscosity of 104 dPa·s of at most 1350° C. The glass has a viscosity versus temperature profile and a coefficient of thermal expansion versus temperature profile of the glass are such that a variable (750° C.−T13)/(CTELiq−CTESol) has a value of at most 5*106 K2. The CTELiq is a coefficient of linear thermal expansion of the glass above a glass transition temperature Tg, the CTESol is a coefficient of linear thermal expansion of the glass in a temperature range from 20° C. to 300° C., and the T13 is a temperature at which the glass has a viscosity of 1013 dPa·s.

Abstract: The invention relates to a coated glass substrate or glass ceramic substrate with resistant, multi-functional surface properties, including a combination of anti-microbial, anti-reflective and anti-fingerprint properties, or a combination of anti-microbial, anti-reflective and anti-fingerprint properties where the substrate is chemically pre-stressed, or a combination of anti-microbial and anti-reflective properties where the substrate is chemically pre-stressed. The coated glass substrate or glass ceramic substrate exhibits a unique combination of functions which are permanently present and do not exert a negative effect on each other.

CPC classification number: C03C3/093 , C03C21/002
Abstract: A glass element is provided that is made of a glass having SiO2, Al2O3, B2O3, and Na2O. The glass has a scratch tolerance that when scratches of 1 mm length are introduced using a Knoop diamond indenter which presses upon a surface of the glass with a force of 4 Newton and is displaced along the surface with a traverse speed of 0.4 mm/s, not more than 20% of the scratches have a noticeable width including visible chipping of more than 25 μm. In some embodiments, the glass, after chemical tempering, has sodium ions that are at least partially exchanged for potassium ions so that a compressive stress zone is provided at the surface of the glass. The compressive stress is at least 700 MPa and an exchange depth of alkali ions is at least 25 μm.
