Usually, the inorganic components are 95 to 75% by weight of ribs and 5% by weight of Mn.
It is a Mo-Mn metallization paste consisting of ~25% by weight. For example, when alumina ceramics having an alumina purity of about 80 to 96% were bonded using this metallizing paste, a practically sufficient adhesive strength was obtained.

してなるメタライズペーストＭｉ戒物にある。That is, the gist of the present invention is that Mn and Mo are the main inorganic components, and aluminosilicate, CaO and TiOz are
The metallized paste Mi Kaimono contains 5 to 20% by weight of Mn and the old volume in total.
アルミノ珪酸塩は、一般にいわれる粘土鉱物粉末でよく
、カオリン等がその代表的なものである。The aluminosilicate may be a commonly known clay mineral powder, and kaolin is a typical example thereof.
これらは一般に結晶水を含んでいるため、４００℃以上
に加熱して脱水して使用した方がよい。Since these generally contain water of crystallization, it is better to heat them to 400° C. or higher to dehydrate them before use.
ＣａＯは、市販のＣａＯ粉末やｉ 、 ｏｏｏ℃以上で

少ない。Even if any of aluminosilicate, CaO, and TiO□ is missing in the metallization paste, the adhesive strength will not improve. In addition, their total amount is 5 to 2% of the total amount of liver and Mo.
The amount is 5% by weight, and if it is outside this range, there is little improvement in adhesive strength.

るのが好ましい。A metallized paste is obtained by kneading these inorganic components and organic components such as a binder and a solvent. Examples of the binder include ethyl cellulose, nitrocellulose, and acrylic polymer. A solvent suitable for the required drying rate is used, and for example, for screen printing, α-terpineol, butyl calpitol, and the like having a boiling point of around 200° C. are preferable. For kneading, a mortar, a ball mill, or the like may be used, but it is preferable to use a three-roll mill.
