Abstract
A glass composition for a plasma display panel (PDP) and its fabrication method are disclosed. The composition, comprising a ZnO—B2O3 group and alkaline earth metal oxide, is environment-friendly, has a high discharge efficiency and is used as various PDP dielectric materials. The fabrication method allows to compose the low melting point unleaded non-alkali glass composition at a low cost.

A glass composition of a PDP comprising:
- ZnO—B2O3 group and
- alkaline earth metal oxide.
A method for fabricating a glass composition of a PDP, comprising:
- mixing 10˜40 mol % of ZnO, 10˜40 mol % B2O3, 10˜25 mol % of alkaline earth metal oxide and 15 mol % or less Bi2O3;
- and
- melting the mixture at a high temperature, quenching the melted component to form a glass flake, milling the glass flake to form unleaded non-alkali glass powder.
A glass composition of a PDP comprising:
- 10˜40 mol % of ZnO and B2O3 each having a ratio of 0.5˜1.5;
- 10˜24 mol % of alkaline earth metal oxide;
- 15 mol % or less Bi2O3;
- and
- 10 mol % or less additive for heightening a glass durability and preventing crystallization.
