preparation example Construction

[0061] As the conductive metal particles used in the production method for forming the conductive powder for electrodes, any metal particles having excellent conductivity can be used, but it is preferable to use metal particles selected from silver (Ag), gold, palladium, platinum, copper, aluminum, At least one substance in the group consisting of tungsten, molybdenum and alloys formed by two or more of the aforementioned metals. Among them, silver (Ag) is most preferable because of its excellent conductivity.

[0062] In addition, the inorganic oxide particles preferably have an average diameter in the range of 1 μm or less, more preferably 10 nm to 500 nm, further preferably 10 nm to 50 nm. The smaller the average diameter of the inorganic oxide particles, the more preferable. When it is larger than 500 nm, it is difficult to obtain a uniform coating; and when it is smaller than 10 nm, it is difficult to obtain inorganic oxide particles having such a small average diameter....

Embodiment 1

[0096] 100 parts by weight of a silica solution (water glass) (manufactured by FERRO Co.) containing 15 wt % of silica particles with an average particle diameter of 50 nm was mixed with 300 parts by weight of amorphous silver (Ag) powder (DOWA Hightech Co., Ltd. ., spherical particle shape) mixing. Then, the mixture was stirred, sprayed, and baked at 580° C. for 60 minutes to prepare conductive electrode powder.

Abstract

The present invention provides a conductive electrode powder which includes electroconductive metal particles, and an inorganic oxide coating layer covering the surface of the electroconductive metal particles. By using a conductive electrode powder, the corrosion, the ionization, the migration such as ionization, and yellowing of the electrode such as colloidalization can be prevented, while simultaneously maintaining electrical conductivity of an electrode.

Description

technical field [0001] The invention relates to a conductive electrode powder and a preparation method thereof, a preparation method of an electrode of a plasma display screen and a plasma display screen containing the electrode. In more detail, the present invention relates to a conductive electrode powder capable of suppressing oxidation of exposed ends of address electrodes and bus electrodes, a preparation method thereof, a preparation method of an electrode of a plasma display panel, and a plasma display panel including the electrode. Background technique [0002] Plasma display (PDP) is a flat display device using plasma phenomenon. When a voltage higher than a certain level is applied to two electrodes separated from each other in a gas atmosphere in a non-vacuum state, a discharge will occur in the screen, so the The above-mentioned plasma phenomenon is also called gas discharge phenomenon. [0003] This gas discharge phenomenon is used to display images on plasma s...
