Piezoelectric properties of (Pb/sub 1-x/Sr/sub x/)/sub 2/NaNb/sub 5/O/sub 15/ ceramic

The authors use x-ray diffraction and electrical methods to study the structure, thermal expansion and piezoelectrical properties of a hot-pressed ceramic corresponding in composition to Pb/sub 2/NaNb/sub 5/O/sub 15/-Sr/sub 2/NaNb/sub 5/O/sub 15/. The structure consisted of tetragonal tungsten bronze phases with an orthorhombic distortion. It was found that when the ratio of lead to strontium is equal the solid solution exhibits a morphotropic boundary near which the piezoelectricity of the ceramic increases sharply.
