Description
2a、2b 電極
本発明に係る圧電磁器組成物は、少なくともSr、Bi、及びNbを含有したビスマス層状化合物、例えばSrBi2Nb2O9を主成分とし、前記主成分100重量部に対してCuをCuOに換算して2重量部以下(ただし、0重量部を除く。)含有している。
焼結後の主成分組成が組成式:(Sr0.9Nd0.1)Bi2Nb2O9を満たすようにSrCO3、Nd2O3、Bi2O3、及びNb2O5を秤量した。続いて前記主成分100重量部に対して焼結助剤としてのMnCO3を含有量が0.5重量部となるように秤量した。これら秤量物を粉砕媒体としてのジルコニアボールが内有されたボールミルに水と共に投入して混合し、十分に湿式粉砕を行った。そしてその後、脱水・乾燥処理を行い、温度800℃〜1000℃で仮焼処理を行って仮焼物を得た。
ここで、Sは主面の面積(m2)であり、マイクロメータを使用して試料の直径を測定し、該直径から算出した。Δtは単位時間当たり温度変化を示す。
焼結後の主成分組成が組成式:SrBi2(Nb1.9Ta0.1)O9を満たすようにSrCO3、Bi2O3、Nb2O5、及びTa2O5を秤量した。続いて前記主成分100重量部に対して、焼結助剤としてのMnCO3を含有量が0.5重量部となるように秤量し、これら秤量物を粉砕媒体としてのジルコニアボール及び水と共に、ボールミルに投入して混合し、湿式粉砕を行った。そしてその後、脱水・乾燥処理を行った後、温度800℃〜1000℃で仮焼処理を行って仮焼物を得た。
主成分は異なるが類似の組成系であるSBTi系圧電磁器組成物について、CuO含有量と焦電係数Tpとの関係を調べた。
