PIEZOELECTRIC NIOBATE TUNGSTEN BRONZE CERAMIC
A piezoelectric ceramic is expressed by the composition formula 100[(Sr 2-x Ca x ) 1+y/4 Na 1-y Nb 5-2/5z Mn z O 15 ]+±SiO 2 (in the formula, 0 ¤ x < 0.3, 0.1 < y < 0.6, 0 < z < 0.1 and 1 < ± < 8) and constituted by polycrystal of tungsten bronze structure, wherein the degree of orientation of axis c of the polycrystal is 60% or more in Lotgering factor. The piezoelectric ceramic offers excellent temperature characteristics and supporting high-power driving.
