(1) The temperature property of resonant frequency of Pb(Sn1/2Sb1/2)O3-PbTiO3-PbZrO3 ternary system was studied, and it was found that the three dimensional expression, composition-frequency constant-temperature, would give us better scope than the two dimensional expression; e.g. the composition- temperature coefficient of resonant frequency, which has been widely used.
(2) The composition which gives minimum frequency constant was constant value independently modes of vibration, and it was found that the mixing ratio of ferroelectric tetragonal and rhombohedral phase was approximately 1 to 1 at this composition which was considered as the center of morphotropic phase boundary.
