Therefore, [Embodiment] & w A partition material for an electric display panel. The investigation of Shifen and other people can clearly know:

When using Zn〇BQ powder, even if the content of BaO is small, Zn〇-B2 03 glass powder can be pushed, and the rabbit can form a light-transmitting partition. . This ^ is caused by the fact that this kind of Zn〇_ metaphysical surface is easy and easy to get close to the refractive index of Tian Andalusite. Hereinafter, the partition wall forming material of the present invention will be described in detail. The partition wall forming material for a plasma display panel of the present invention contains ^ 16767 7 200536799 H-based glass breaking powder and filler powder. Department of broken glass powder 60 to 90 denier. / & Ten b examples are.

The other aspect, such as filling; = long time (that is, 'if the glass powder is less: sexually not; I, so that it is difficult to form a refined glass, the transparency is low. Next to the next door, the material of the present invention, the mullite mullite M 1 is used as a filler powder to oxidize the stone. 4 The andalusite powder can be used for any purpose such as oxidation and so on. Foreign matter to the degree of coffee = rich 1 Lu Andalusite powder, for example, then in addition, this = boots can be fired within the range of the boots.. Finally, Weixiang can use all the filler powder as the andalusite powder. You can also use other methods to adjust the thermal expansion coefficient to introduce the heat exchanger and oxidize the oxidizing agent. For the purpose of improving shape retention, Tao Wanchong, except for one year old, such as Dong Yueshi (⑶rdiente), etc. # The andalusite powder accounts for 20 to 100% by mass of the filler powder, preferably 25 To 100% by mass and 100% by mass. If the proportion of mullite powder is small, the light transmission of the obtained partition wall is reduced. 50% of the mullite powder used in this application The average diameter is smaller than 3] 6767 200536799, preferably 0.5 to 6 / zm, and particularly good, the average diameter is 0 to 6 at the end. When the average diameter is too small, the To adjust the rheological ceramics and also increase the cost. In addition, when the average particle size of the medium and difficult to increase, there is a tendency of shape retention to deteriorate. !: Lb?; ~, W For filler powders other than andalusite, = 〇 田田 :: workite stone% for the same reason, it is preferred to use the average particle size in the range of 0.5 to 6 ^. However, if used Dioxin impairs the light transmission of the next door, and it should not be used in the present invention. Zn, B2 used in the present invention. The 3 series glass powder is a glass containing Zn〇 and b203 as a main component. Examples of such glass are%: Zn〇 contains 3% or more, and b203 contains 15% by mass or more. Moreover, compared with It is a kind of glass that does not contain Ba0, or does not exceed M% by mass even if it contains rhenium. The reason is because glass in this range is equipped with smullite rather than alumina. The powderer is advantageous in making a partition with excellent light transmission. For example, it can be removed from the material of the partition.

When Pb0 is used as the purpose, it is necessary that Pb0 is not more than% by mass, and it is preferable that Pb0 is not contained at all. Examples of suitable compositions of ZnO-B203-based glass include, by mass percentage, 30 to 60% of Zn0, 15 to 35% of b203,

Ba〇 〇 to 25%, Si〇 2 3 to 20%, Li20 0.2 to 6〇 / 〇,

Li20 + Na20 + K2 01 to 12% of BaO_ZnO_B203 glass. The glass having the above-mentioned composition can be a partition wall material that can be fired at a temperature of 600 ° C or lower, especially at a low temperature of about 56 ° C. In the following, each component is described by adding 316767 9 200536799.

ZnO system reduces the softening point while reducing the thermal expansion coefficient of x ^ A j, and its content is 30 to 60%, which is 3 5 to 5 5%, and more preferably 3 7 compared to A μ sc To 54%. For example, if ZnO is 30% and less than RT ^ 丄, and / ° is less than 4, the above-mentioned effect cannot be obtained, while if it is above 60 and θ 守, ^ 7 will be precipitated and crystallized in the glass so that sintering cannot be obtained. body. ≫, β2 03 is a component constituting the skeleton of glass, and its content is from 3 to 35%, preferably from 16 to 33%. When the taxi 103 is 15% or less, it is difficult to vitrify. On the other hand, if ,,,, 3 ~ 〇3 is at 35%, the softening point is south, and the temperature is below 60 ° C, the four broken planters α Shigan Zhibu, Diandu; Wucheng It is difficult to obtain a delicate grilled bass body, and as a result, the panel characteristics are reduced. '° ▲ BaO is a component that stabilizes glass, and its content is 0 to 25%, preferably 3 to 25%, more preferably 4 to 23%, and particularly preferably 5 to 2 ()%. Although it is not an essential ingredient, if it is less than 3%, the glass will be unstable and easy to crystallize, so that the adhesion to the dry film is not good, or crystals will precipitate when firing as a barrier-forming material. In the case of obtaining a fine sintered body. On the other hand, if it is more than 25%, the thermal expansion coefficient will increase, and it will be unsuitable to adjust to the glass of the glass substrate so that the light transmittance is reduced.

Si 〇2 仏 forms a skeleton component of glass, and its content is 3 to 20%, preferably 4 to 17%, and more preferably 4 to 16%. If the meaning is above the above, the glass will be unstable, and if it is above 20%, the softening point will be too south to make it difficult to fire at a temperature below 560 ° C. The component of the 20 series which significantly reduces the softening point of the glass is 0.2 to 6%, and the softness is 5 to 5. /. . If U20 is less than 0.2%, it is not confiscated because the softening point of 316767 10 200536799 is not confiscated. On the other hand :: Secondly, it is difficult to be sintered at a temperature lower than that of electricity, and it is easy to crystallize. = Xi ==, then the glass will significantly reduce the adhesiveness between the firing walls of the apparently disturbing barrier-forming material, so as another Then, crystals are precipitated and a delicate sintered body cannot be obtained. ′ In order to maintain the stability of the glass w > 丄 The purpose of adding more L1220 Japanese yen f, and the component 22 of the neutralization point of the glass by thermal method is to reduce the softness of the glass like L12. Content :; The adhesion between the membranes is reduced, or |, II, the son-in-law's sex is reduced, and dry thin ^ ^ ^ PP ^ ... method to obtain delicate fired bodies, so the ideal content is limited to: Na2〇 It is 9〇 / 丨,; π soil 6% is below T f ^ # ◦, preferably 8% or less, particularly preferably 6 / 〇 or less, dagger 20 is less than 6%, especially preferably. the following. ★ To:? = In terms of the total content of L120, Na20 and K20, from L%, preferably 2 to 10%. If the total amount is below 1 °, the softening point of glazing is not sufficiently reduced. Therefore, it is difficult to sinter at a temperature below 5 ° C. On the other hand, when the amount of the domain is more than 12%, it is easy to crystallize, the adhesion with the dry film is reduced, or the durability of Poin is not good. When a metal inspection component is added, the adhesion to the dry film tends to decrease. Therefore, in order to improve the adhesion, you can also add To3. However, if the amount of MA is increased, it is preferable to limit it to 1.5% or less due to the increase in the pupation point. In order to stabilize the glass, it is preferable to make the ratio of Ba0 / (BA3 + si0,) (in the range of M to 0.8. When such a ratio is less than 0m, the glass will be unstable, During the firing of the wall-forming material, 316767 11 200536799 is precipitated, and it is difficult to form a fine sintered body. Moreover, when such a ratio is more than two, the thermal expansion coefficient of the partition-wall forming material increases. However, it is difficult to adjust the glass of the glass substrate. A more preferred range is 015 to 〇6. 'Inside, the above ingredients are not included' is within the scope of not affecting the effect of the present invention. ° ~ Add other ingredients. For example, to improve water resistance Resistance or chemical resistance to 1 gas, or Ta205 (oxidized surface), La203 (oxidized sharp) ^ = ^ continued butterfly, plus win titanium), called 05 (relative to oxidation " stability, you can also add P205 (Oxidized scale). In addition, the additive amount of the components such as bismuth is limited to 15% or less, preferably / 0 or less, more preferably 12% or less, and particularly preferably 10% or less.
