1.Pb0.988V0.012Zr0.504+xTi0.472-xNb0.024O3という組成においてNbをドーピングしたAgのないセラミックスがモルフォトロピック相境界に有利に整合すると判明したこと。式Pb0.988V0.012Zr0.504Ti0.472Nb0.024O3によれば適切な分析組成が実現され、これによって許容可能な変位において圧電損失が僅かになる。
2.焼結中にCu2Oを規定どおりに組み込み、Nbの組み込みおよび適切な焼結温度により結晶サイズの成長を制御することによって、アクチュエータの変位と損失エネルギーが決定される。
3.Nb2O5の組み込みは、925゜Cの空気中で原材料混合物が残りの酸化物混合物といっしょに反応している間にすでに行われる。
4.セラミックスPb0.988V0.012Zr0.504Ti0.472Nb0.024O3をCu内部電極とともに、Cu/Cu2Oのバランスに対応する低減された酸素分圧で焼結した後では誘電率と温度の依存性は、Ndをドーピングしたセラミックス質量体Pb0.97V0.01Zr0.55515Ti0.4485O3を使用した場合よりも低い。
