Abstract
PURPOSE:To make polarization possible with a small electric field intensity, in a low polarization temperature and during a short time as well by limiting a component ratio within a specified range. CONSTITUTION:A substance having the molecular formula (1) is a main component [0.15<=X<=0.40, 0<=alpha<=1 in the formula (1)], and 0.05-20wt% of MnO2 is added as an annex to 1mol weight of the main component, and furthermore 10wt% of In2O3 is added as an annex to 1mol weight of the main component if necessary. The reason for limiting X of the main component within 0.15-0.40 is that evaporation of PbO occurs in baking process in case of taking a value below 0.15 and polarization condition becomes difficult because of shifting of polarization condition into a high temperature and a high voltage. On the contrary piezoelectricity become lower in case of a value over 0.40. And substitution of La and Nd into Pb position is effective even if one of them is taken, so alpha is taken to be 0-1.
