Description
Pb1.015Zr0.44Ti0.46(Zn1/3Nb2/3)0.10O3.015・・・(1)。
この組成は、優れた圧電特性を示し、チタン酸ジルコン酸鉛(PZT)のBサイトをPb(Zn1/3Nb2/3)O3で10モル%置換している。Pbサイト比は1.015でありストイキオメトリーよりも過剰である。この場合、圧電材料ペーストは、以下のようにして作成することができる。純度99.9%以上の酸化鉛(PbO)、酸化チタン(TiO2)、酸化ジルコニウム(ZrO2)、酸化亜鉛(ZnO)、酸化ニオブ(Nb2O5)粉末を原料に、固相法により組成式(1)に示すモル比の圧電材料組成粉末を調製する。なお、圧電体層の焼結温度を900℃未満とするために、粉末の粒径は0.5μm未満とする。
