Abstract
【解決手段】 (a)伝導性金属と、(b)結晶化ガラスと、(c)非晶質ガラスと、(d)有機媒体とを含む厚膜組成物。当該組成物は、バナジウム、マンガン、鉄、コバルト及びそれらの混合物の酸化物の中から選択された遷移金属酸化物の微細粒子をさらに含むことができる。当該伝導性金属は、銀、金、白金、パラジウム、およびそれらの混合物からなる群から選択される。
【選択図】 なし
Description
上記のように、厚膜導体組成物の調製に使用される金属は、典型的には、銀、金、白金、およびパラジウムから選択される。これらの金属およびこれらの混合物は、いずれも本発明に使用することができる。さらに、厚膜組成物の非伝導性成分に対する伝導性成分の比率を制御することによって、組成物の伝導率を操作することができる。
上記のように、本発明の組成物は2種の無機バインダー(非晶質ガラスおよび結晶化ガラス)を含む。
非晶質ガラスバインダーの化学組成は、本発明の機能にとって重要性が低い。例えば、ホウケイ酸鉛は、自動車ガラスのペーストに広く使用されており、本発明の実施にも同様に使用することができる。
結晶質材料は、秩序のある周期的な原子配列を有するものとして定義され、X線にかけると明瞭な回折ピークを生じる。この結晶質構造は、原子の長期間秩序をもたない不規則な配列を有し、X線回折パターンを散乱させる、一般的なガラスとは対照的である。結晶化ガラスバインダーが焼成中のピーク温度の範囲で十分な結晶性を示すことは、当該バインダーの機能にとって重要である。組成物は580から620℃で焼成されるので、結晶化点は300から610℃の範囲内が好ましく、500から610℃が最も好ましい。
本発明の実施において、遷移金属酸化物は、耐摩耗性を向上させるために使用される。適切な酸化物は、遷移金属である、バナジウム、マンガン、鉄、およびコバルトの酸化物を含む。所望の効果を達成するのに必要な量は、ペースト基準で3.0から15重量%、好ましくは5.0から10.0重量%である。3.0重量%未満では、耐摩耗性の向上を期待することはできない。さらに、遷移金属の量が、組成物の総重量基準で15重量%より多ければ、抵抗率が増加し、かつ、焼結は不利な影響を受ける。
本発明の金属組成物は、一般的には、所望の回路パターンに印刷できるペーストに形成される。
以下の手順を用いて、引き続き記載される実施例の評価用の小規模な除曇回路を作製した。
(1)耐摩耗性
印刷および焼成後の導体パターンの蛇行する中心を、#400のサンドペーパーで摩擦し、抵抗率の変化を調べた。抵抗率(R)の測定は、20回の摩擦サイクル(往復10回)ごとに1回行った。この値を、R/R0の比を用いて初期の抵抗率(R0)と比較した。
蛇行形状に印刷し焼成した銀ペーストの抵抗を、Hewlett Packard 347 8Aマルチメーターを用いて測定し、体積抵抗率として算出した。
