【発明の詳細な説明】
「産業上の利用分野」
本発明ムライト磁器は、ＩＣパッケージ、プリント配線
基板等の電気絶縁体に好適に利用される。DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Use" The mullite porcelain of the present invention is suitably used for electric insulators such as IC packages and printed wiring boards.
「従来の技術」
従来のムライト磁器は、カオリン、粘土など比較的不純
物の多い原料を用いていた。``Conventional technology'' Conventional mullite porcelain uses raw materials with relatively high impurities such as kaolin and clay.
「発明が解決しようとする課題」
しかし、近年、配線の高密度化、使用周波数の高領域化
に伴い、従来のムライト磁器では電気特性、機械的強度
、メタフィズ強度、クリストバライトの副成分等の点で
不十分な水準にあった。"Problems to be Solved by the Invention" However, in recent years, with the increase in the density of wiring and the use of higher frequencies, conventional mullite porcelain has suffered from problems such as electrical properties, mechanical strength, metaphys strength, and subcomponents of cristobalite. was at an unsatisfactory level.
本発明は、かかる要請に応じるムライト磁器を提供する
ことを目的とする。An object of the present invention is to provide mullite porcelain that meets such demands.
「課題を解決する几めの手段」 その第一の手段は、磁器の組成を重量基準で。“Elaborate means to solve problems” The first method is to determine the composition of the porcelain on a weight basis.

二〇主段は、第一〇主段においてＮａｚＯを含ませない
ところにある。K, 0.2 to 1%, one or more selected from BaO and MgO, 1 to 8%, NaIQ, 5% or less, and the remainder mainly mullite. 〇 NazO is not included in the main stage.
「作用」
ＫｓＯは適量の存在によってメタツイズの密着強度を肱
めるもので、０．２ ％に満たないとその作用に乏しく
、ｔＳをこえると機械的強度の低下をも友らす。ＢａＯ
及びＭｇＯはいずれもムライトの結晶化を促進するとと
もに、機械的強度を高めるほか、就中ＢａＯは誘電損失
を下げる。"Effect" The presence of an appropriate amount of KsO improves the adhesion strength of MetaTwiz, and if it is less than 0.2%, the effect is poor, and if it exceeds tS, it also causes a decrease in mechanical strength. BaO
Both of these and MgO promote crystallization of mullite and increase mechanical strength, and BaO among others lowers dielectric loss.
但し、これらの含量が１％に満たないとクリストパフイ
トの残存をまねくほか、上記の作用に乏しく、８％をこ
えると却りて強度が低下する。However, if the content is less than 1%, cristopaphite may remain and the above-mentioned effects will be poor, and if it exceeds 8%, the strength will actually decrease.
ＮａｚＯは０．６％までなら悪影響を及ぼさないが、０
．５％をこえると誘電損質を大きくし、強度を低下させ
る。NazO has no adverse effects up to 0.6%, but 0.
．． If it exceeds 5%, dielectric loss increases and strength decreases.
なお、ムライトの原料は合成ムライト磁器に限定される
ことなく、シリカとアルミナの各粉末を使用しても良い
。この場合、シリカとアルミナの比率は理論組成に限定
されず、（Ａｈ Ｏｓ ／５ｔ（ｈ）モル比≦２を満比
す範囲でＡｌｇＯｓが過剰であっても良い。Note that the raw material for mullite is not limited to synthetic mullite porcelain, and silica and alumina powders may also be used. In this case, the ratio of silica to alumina is not limited to the theoretical composition, and AlgOs may be in excess within the range of (Ah Os /5t(h) molar ratio≦2).
