Problems solved by technology

The shape of the mercury introduction device filled with the original getter composition is cylindrical, spherical or rod-shaped, and there is no groove for releasing mercury, or even if there is a groove for releasing mercury, its width is very narrow, so mercury The release effect is not high
[0014] In addition, after the getter composition is pressed into the metal structure, in the case of a getter that generates slits due to the overlapping of plates, dust is severe during the manufacturing process, and th...

Embodiment 2

[0066] Example 2 is an example in which the content of Zr and Al was reduced in the composition of Comparative Example 1, and 2% by weight of Ti was added. After adding Ti, it can be seen that the mercury release rate is 1% higher than that of Comparative Example 1.

Embodiment 3

[0067] Example 3 is an example in which 2 wt % Ta is added to the composition of Example 2. Compared with Example 2, the mercury release efficiency was increased by 4% due to the addition of Ta.

[0068] In addition, when Example 1 and Example 3 are compared, even in a composition containing 2 wt % Ta, the mercury release rate can be improved by reducing the Zr and Al contents and adding 2 wt % Ti.

Embodiment 4

[0069] In Example 4, 1 wt % of Fe was added to the composition of Comparative Example 1. Compared with Comparative Example 1, the mercury release rate of Example 4 was increased by 2%.

[0070]In Examples 5 and 6, in the composition of Comparative Example 1, 2 wt % of Ta was added, and Fe was added in a small amount to produce a getter composition. In this case, the mercury release rate was 6 to 7% higher than that of Comparative Example 1.

Abstract

The invention relates to a getter combination which is used on back light units as LCD TV and monitor and used for leading mercury in an external electrode fluorescent lamp or a cold cathode adding Ti to the getter combination made from Ti-Hg Zr-Al to raise the adsorption efficiency of getter and prevent getter from being oxidized owing to the inoxidability of Ti; adding Ta to raise the release effect of mercury and to reduce the activation temperature by 100 DEG C; the activation can also be carried out from 550 to 650 DEG C; therefore, the getter combination can be prepared by making use of common stoves or gas flames used in the lamp manufacturing procures without expensive high-frequency equipment, and the electrode is damaged to minimum extent. Besides, with adding 0.05 to 5 percent of Fe to the getter combination, the release effect of mercury is raised, the cost of raw material is reduced, and the activation effect is raised with the same function as medium in the getter activation process.

Description

technical field [0001] The present invention relates to a getter composition for introducing mercury into an EEFL (External Electrode Fluorescent Lamp) or a CCFL (Cold Cathode Fluorescent Lamp) used as a BLU (Back Light Unit) of an LCD TV, a display, etc., and a getter composition thereof. device. Background technique [0002] Usually, a getter is manufactured and used by mixing a plurality of metal components according to the composition of the residual gas to be removed and the conditions of use, and has the property of chemically absorbing the gas to be removed. [0003] Getter compositions can be made in a mixture of metal forms, and can be formed in a variety of structural or compound states, however, the ultimate goal is to stably retain mercury and be easily activated within the luminaire according to specific temperature conditions , so that it is easy to release mercury, and it is easy to absorb the doping gas in the lamp. In addition, once the lamp is complete, t...
