Piezoelectric material, piezoelectric element, and electronic device
Abstract:
A piezoelectric material that does not contain lead and has excellent piezoelectric constant and mechanical quality factor in a device driving temperature range (−30° C. to 50° C.) is provided. A piezoelectric material includes a main component containing a perovskite metal oxide represented by following general formula (1), and a first auxiliary component containing Mn, wherein an amount of the contained Mn is 0.002 moles or more and 0.015 moles or less relative to 1 mole of the metal oxide. (Ba1-yBiy)a(Ti1-x-zZrxFez)O3  (1) (where 0.010≦x≦0.060, 0.001≦y≦0.015, 0.001≦z≦0.015, 0.950≦y/z≦1.050, and 0.986≦a≦1.020).
