J.Am.Ceram.Soc.,52(1976)276 J.J.Appl.Phys.,13(1974)1291
12a、12b 電極
なお、表1に示した各試料は、上記一般式aMnO2+bSiO2におけるaおよびbの値が0の試料(すなわち、Mn酸化物およびSi酸化物を副成分として含有させていない試料)である。
表1において、試料番号に「*」を付していないものは本発明の範囲内にある実施例の試料であり、試料番号に「*」を付したものは本発明の範囲外の比較例の試料である。
また、表2において、試料番号に「*」を付していないものは請求項1の要件に加え、請求項2の要件をも満たす試料であり、試料番号に「*」を付したものは本発明の請求項1の要件は備えているが、請求項2の要件を備えていない試料である。
また、表3には上述の単結晶の例を示している。
なお、表2の試料番号43〜47のdの値が、表1の試料番号2〜5のdの値と異なっているが、これは副成分であるMn酸化物,Si酸化物の添加の影響によるものであり、表2の試料番号43〜47と、表1の試料番号2〜5におけるdの値の差程度であれば、特性に与える影響はほとんどないものと考えられる。
したがって、本発明は、圧電セラミック素子、電歪セラミック素子、電気光学効果素子、光高調波発生素子等の非線形光学素子などの分野に広く利用することが可能である。
