ミック組成物にガラスを含ませるが、ガラスは遮光性に
劣る故、特に遮光性の確保が必要となる。In addition, in order to reduce circuit resistance, low-temperature fired ceramics that can be fired at temperatures below 1000°C are used when circuit wiring patterns are formed using highly conductive metals such as gold, silver, and copper. It will be done. This low-temperature fired ceramic contains glass in the ceramic composition, but since glass has poor light-shielding properties, it is particularly necessary to ensure light-shielding properties.
このため従来においては、セラミックに遮光性を与える
ために、セラミック組成物に着色剤を添加して焼成し、
着色セラミックを得ていた。For this reason, in the past, in order to provide light-shielding properties to ceramics, colorants were added to ceramic compositions and fired.
I was getting colored ceramics.

（発明が解決しようとする問題点）
ところで従来においては、遮光性に最も優れる黒色系の
着色剤には適当なものがなかった。(Problems to be Solved by the Invention) Conventionally, there has been no suitable black coloring agent that has the best light-shielding properties.
黒色とするためには、赤と緑、すなわち酸化鉄と酸化ク
ロム等、複数の金属酸化物を混合した着色剤を用いるこ
とが考えられる。In order to obtain black color, it is possible to use a coloring agent that is a mixture of multiple metal oxides such as red and green, that is, iron oxide and chromium oxide.
しかし、単独の金属酸化物を用いるときには問題となら
ないが、これらの複数の金属酸化物を混合した着色剤に
あっては、セラミック組成物に添加して焼成する際に、
着色剤間、もしくは着色剤とセラミック組成物間に反応
が起こり、目標とする色調が出なかったり緻密なセラミ
ックが得られないという問題点がある。However, this is not a problem when using a single metal oxide, but when using a colorant that is a mixture of these multiple metal oxides, when it is added to a ceramic composition and fired,
There is a problem in that a reaction occurs between the colorants or between the colorant and the ceramic composition, resulting in a failure to obtain the desired color tone or to obtain a dense ceramic.
そこで本発明は上記の問題点を解消すべくなされたもの

てもセラミックは黒色を呈する。Iron chromate added as a coloring agent is FeCr2O+
It has a spinel-type chemical composition and is thermally stable. That is, it is stable even when heated to the firing temperature of the ceramic composition. For example, in the case of a low-temperature firing ceramic composition that is made of a mixed powder of glass and alumina and can be fired at 1000°C or less,
Iron chromate is stable under temperature conditions of about 0° C. without reacting with alumina and glass components, and the ceramic exhibits a black color. In addition, in the case of alumina ceramic using alumina powder in the ceramic composition, the temperature is approximately 1600℃.
Although the ceramic is fired at a high temperature of approximately 1,600°C, it remains black in color.
