PIEZOELECTRIC PORCELAIN COMPOSITION |
| 摘要 |
<p>A KNbO3-NaNbO3 piezoelectric porcelain composition which exhibits a larger piezoelectric constant than those of conventional ones and does not have any secondary phase transition point in the neighborhood of room temperature (10 to 40°C), that is, a piezoelectric porcelain composition represented by the general formula: (1-y-z-w)(KxNa1-x)NbO3 + yLiNbO3 + zSrTiO3 + wBiFeO3 wherein (KxNa1-x)NbO3 represents potassium sodium niobate; LiNbO3 represents lithium niobate; SrTiO3 represents strontium titanate; and BiFeO3 represents bismuth ferrate; with the proviso that 0.4<x<0.6, 0<y=0.1, 0<z<0.1, 0<w<0.09, and 0.03<y+z+w=0.12.</p> |
