Silico-sodo-calcic glass composition, to manufacture 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 (1-9%, preferably 1-7.5%), calcium oxide (7-11%), and strontium oxide (3-9%, preferably 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.
