In particular, the present invention relates to a ceramic material having a general chemical formula (I): (I): x(Bi0 .5 Na0 .5 )TiO3- Y(Bio.5K0.5)TiO3-ziSrHf03-z2SrZr03, wherein x+y+Z1+Z2 = 1; y, (z1+ z2)0 0; x > 0. In embodiments, the present invention also relates to a ceramic material having a general chemical formula (II): x(Bi0.5Nao.5)TiO3-y(Bi0.5K0.5)TiO3-ZiSrHf03-z2SrZr03, wherein x+y +z-i+z2 = 1; x, y, fa + z2)0 0; as well as a ceramic material of general formula (III): y(Bi 0.5 K 0.5 )TiO 3 -ziSrHf0 3 -z 2 SrZr0 3 , wherein y +zi,+z2 = 1; y, (zi + z2)0 0. 00 O O
