Description
ガラス組成物の組成は、酸化物換算で、V2O5が62〜92重量%、P2O5が5〜20重量%、Li2O、Na2O、K2O、Cu2O及びAg2Oのいずれかが1〜15重量%、WO3、MoO3、Fe2O3、MnO2、BaO、Sb2O3及びBi2O3のいずれか1種以上が0〜20重量%である。
(ガラス組成物の作製)
ガラス組成物の作製は、以下の手順で行った。
ガラスの特性温度は、ガラス粉末を用い、示差熱分析(DTA)によってピーク温度より求めた。測定用試料は、スタンプミルを用いて粉砕し、ガラス組成物の粉末を作製した。
得られたガラス組成物を10×10×4mmのサイズに加工して試料片とし、この試料片をアルミナ基板に載せて結晶化開始温度より50℃以上高い温度で50時間加熱し、結晶相を生成させた導電性材料を作製した。
次いで、四探針法電気抵抗計Loresta AP(三菱化学(株)製)を用いて、恒温槽中にて20〜40℃における試料の抵抗率を測定した。得られた抵抗率より抵抗温度係数を算出した。
耐湿性試験は、ガラス粉末を用い、85℃、85%の恒温恒湿槽に48hr(48時間)投入し、粉末が溶解したもの及び二次凝集して固まったものを×(不可)とした。粉末状態のまま外観が変わらなかったものは○(可)とした。
生成する結晶相の割合や結晶子サイズは、ガラス組成や熱処理条件により変化する。
