Piezoelectric compounds of the formula xNa m Bi n TiO3- yK m Bi n- TiO3- zLi m Bi n TiO3-pBaTiO3 where (0 < x <=1),(O<=y<=1),(0<= z<= 1), (0.3<= m<=0.7), (0.3<= n <=0.7), (0 < p<= 1) (0.9<=m/n <= 1.1) as well as to doped variations thereof are disclosed. The material is suitable for high power applications.
L'invention concerne des composés piézoélectriques représentés par la formule xNamBinTiO3- yKmBinTiO3- zLimBinTiO3-pBaTiO3, dans laquelle (0<x =1),(O=y=1),(0= z= 1), (0,3= m=0,7), (0,3= n =0,7), (0<p= l) (0,9=m/n = 1,1) ainsi que des variantes dopées de ceux-ci. Cette matière convient pour des applications à forte puissance.
