Description
ここで比較例を参照する。一連の組成物を電極形成用として調製した。種々の組成物を以下の表1に示すが、これに含まれるサンプルA、B、CおよびDは、先行技術の高ZnO含有量の組成物から作製され、一方、表1のサンプルEおよびFは、本明細書の実施形態に従って、低ZnO含有量の組成物から作製されている。すべてのサンプルは、同じ方法、特に、組成物を混合するステップと、高温の静水圧圧縮によって成形するステップと、引き続いて、1400℃〜1500℃で40時間焼結しその後冷却するステップとを含む方法によって形成した。各サンプルは、表1に示す寸法を有する大型のサンプルブロックとして形成された。
組成の違いが最終的に形成される電極基体の電気抵抗率の変化をもたらすか否かを決定するために、2つの対比サンプルについて試験した。すなわち、実施例1のサンプルAおよびEについて、電気抵抗率における変化を評価するために、100℃〜1000℃の範囲の種々の温度において試験した。前記のように、電気抵抗率の試験は、巨視的な内部亀裂を含まないサンプル部分について行った。また、試験は、直流による4点プローブ法を用いて行った。電気抵抗は、100℃〜1000℃の間、加熱および冷却時の双方において100℃ごとに、Keithley 2750分析器によって測定した。抵抗データと、サンプルの寸法と、プローブの位置とを用いて容積電気抵抗率を計算した。この実施例において報告したデータは、加熱時に測定した容積電気抵抗率である。
