The invention relates to a glass composition intended for the manufacture of thermally stable substrates or panes, which comprises the following constituents in the following proportions by weight:

Silica-soda-lime glass compositions and their applications

Glasses for use as substrates for flat panel displays, having a composition consisting essentially of, as calculated in weight percent on an oxide basis, 38-56 SiO.sub.2, 10-28 Al.sub.2 O.sub.3, 0-4 Li.sub.2 O, 0-6 Na.sub.2 O, 0-15 K.sub.2 O, 4-18 CaO, 0-5 MgO, more than 8 and less than or equal to about 24 SrO, 0-2 ZrO.sub.2, said glass further consisting essentially of Na.sub.2 O+K.sub.2 O in total between about 6 and 18 weight percent.

Glasses for display panels

An optical signal amplifier comprising an optical waveguide fiber integrated by thallium ion exchange in a boron-free silicate glass doped with up to 5 weight % erbium oxide, the glass having a base composition, as calculated in weight percent on an oxide basis, consisting essentially of

Optical signal amplifier glasses

This invention relates to glasses exhibiting refractive indices higher than 1.880, Abbe numbers of at least 29, densities lower than 4.1, good chemical durability and stability against devitrification, and an integrated transmission over the range of 380-800 nm at a thickness of 10 mm greater than 79%, the glasses consisting essentially, expressed in terms of weight percent on the oxide basis, of

Glasses with very high index of refraction and low density

A process for the production of an integrated optical circuit in a glass body by ion exchange between certain regions of the glass body and a metallic salt with the use of a mask defining the regions where the ion exchange occurs, wherein the mask comprises a layer of silicon and the mask is removed by an etching operation preceded by a cleansing operation.
