Silico-sodo-calcic glass composition, useful to prepare substrates for display screen, preferably plasma screen, comprises silicon dioxide, aluminum oxide, zirconium oxide, sodium oxide, potassium oxide, calcium oxide, and strontium oxide

摘要

Silico-sodo-calcic glass composition, to manufacture substrates for display screen, preferably plasma screen, comprises silicon dioxide (55-75%), aluminum oxide (1-5%), zirconium oxide (1-5%), sodium oxide (1-5.5%), potassium oxide (1-7.5%), calcium oxide (7-11%), and strontium oxide (4.5-9%). An independent claim is included for a display screen, preferably plasma screen, comprising two glass substrates separated by a space containing gas-plasma mixture, where at least one of the substrate is constituted of the composition.
