Embodiment Construction

[0026] A glass substrate for a plasma display panel, it is important that each chemical component in the glass substrate is composed as follows by weight percentage:

[0027] SiO 2 50~65%,

[0028] Al 2 o 3 5~15%,

[0029] Na 2 O 0.01~15%,

[0030] MgO 0.01~15%,

[0031] CaO 0.01~10%,

[0032] SrO 0.01~15%,

[0033] BaO 0.01~13%,

[0034] Fe 2 o 3 0.01~1%,

[0035] ZrO 2 0.01~5%.

[0036] The sum of the weights of MgO, CaO, SrO and BaO accounts for 5-30% of the total amount.

[0037] The content of said MgO is preferably 2.07-3.18%.

[0038] The content of said CaO is preferably 2.29-4.43%.

[0039] The content of said SrO is preferably 5.93-9.36%.

Abstract

The invention relates to a glass substrate for a plasma display panel. The glass substrate comprises the following chemical compositions in percentages by weight: 50-60% of SiO2, 5-15% of Al2O3, 0.01-15% of Na2O, 0.01-15% of MgO, 0.0.1-10% of CaO, 0.01-15% of SrO, 0.01-13% of BaO, 0.01-1% of Fe2O3 and 1-5% of ZrO. The invention fills the research and development blank of the glass substrate for the plasma display panel in the optical glass market of China and provides compositions of a material formula for original sheets of the PDP (Plasma Display Panel) glass substrate produced by adopting a float process; and the lighter PDP glass substrate which meets various performance indexes can be produced through the fine proportioning of chemical compositions.

Description

technical field [0001] The invention belongs to the technical field of photoelectric glass production of plasma displays, is especially suitable for float production, and relates to a formula of glass substrates for plasma display panels. Background technique [0002] Plasma display technology PDP is an advanced flat-panel display technology developed along with the development of the electronic industry in recent years. It is the two most important flat-panel display technologies in the civilian market. In particular, PDPs are attracting attention as large flat panel color displays. In the PDP, there are a large number of cells between the front and rear substrates, and images are formed by plasma discharge in the cells, and its working principle is similar to that of a fluorescent lamp. PDP uses a plasma tube as a light-emitting element, and each pixel on the screen corresponds to a separate plasma tube. The screen of the PDP uses glass as the substrate, and the substrat...
