Abstract: There is provided an optical glass, in which a refractive index (nd) at a wavelength of the d line of helium (587.6 nm) is in a range of 1.45000 to 1.65000; an ISO color contribution index ISO/CCI is 0.00 for blue (B), 0.80 or less for green (G), and 0.80 or less for red (R); and an S value is 0.70×106 or more and less than 1.03×106 (Pa/° C.), the S value being obtained by the equation: S=E·α/(1−ν), in which E is Young's modulus (unit: GPa); α is an average coefficient of linear expansion in a temperature range of 100° C. to 300° C. (unit: 10−7° C.−1); and ν is Poisson's ratio.

Abstract: A glass-ceramic article comprises silica, lithia, phosphorus pentoxide, and zirconia in amounts that, when heat treated, provide a glass-ceramic including a lithium disilicate (L2Si2O5) crystalline phase. The glass-ceramic may have high fracture toughness, transparency, hardness, and may be strengthen via ion-exchange.

Abstract: A chemically tempered glass or glass-ceramic article in pane form for use as a cover pane includes a glass or glass-ceramic having a composition comprising the components SiO2, Al2O3, Li2O and Na2O, having a thickness d of 300 μm to 1000 μm, a compressive strength at a distance of 30 μm from a surface of a main face CS30 of at least 60 MPa, and a compressive strength at a distance of 50 μm from the surface of a main face CS50. The compressive strengths CS30 and CS50 of the same main face are in the following ratio V to one another: V = CS 30 CS 50 ≤ - 0.0006 * d + 2 , where d is the thickness of the article in μm.

Abstract: Glass-based articles that include a hydrogen-containing layer extending from the surface of the article to a depth of layer. The hydrogen-containing layer includes a hydrogen concentration that decreases from a maximum hydrogen concentration to the depth of layer. The glass-based articles exhibit a high Vickers indentation cracking threshold. Glass compositions that are selected to promote the formation of the hydrogen-containing layer and methods of forming the glass-based article are also provided.
