Description
B2O3源としてほう酸を、Bi2O3源として酸化ビスマスを、BaO源として炭酸バリウムを、SiO2源として微粉珪砂を、Al2O3源として酸化アルミニウムを、ZnO源として亜鉛華を、Li2O源として炭酸リチウムを、Na2O源として炭酸ナトリウムを、K2O源として炭酸カリウムを、MgO源として炭酸マグネシウムを、CaO源として炭酸カルシウムを、SrO源として炭酸ストロンチウムを使用した。これらを所望の低融点ガラス組成となるべく調合したうえで、白金ルツボに投入し、電気加熱炉内で1000〜1300℃、1〜2時間で加熱溶融して表1の実施例1〜7、表2の比較例1〜4に示す組成のガラスを得た。
厚み2〜3mm、サイズ100mm角のソーダ石灰系ガラス基板に、焼付け後の膜厚が約20μmとなるべく勘案して、アプリケーターを用いて前記ペーストを塗布し、塗布層を形成した。 次いで、乾燥後、630℃以下で10〜60分間焼成することにより、クリアな誘電体層を形成させた。
での伸び量から求めた。
低融点ガラス組成および、各種試験結果を表に示す。
