| Popis: | Fluorinated lead zirconate titanate piezoceramics are prepared using mechanical activation of the starting mixture and synthesized ceramic powder in a vibratory mill, and their physical properties are studied. The introduction of fluorine (1–5 mol %) into the starting mixture enhances the dielectric rigidity of the material. The addition of 0.1–0.3 mol % F in combination with 0.3–3 mol % Fe makes it possible to produce hard piezoceramics capable of operating in electric fields of up to 3 kV/cm. The ceramics have a tetragonally distorted perovskite structure and consist of grains 1–2 em in size. X-ray microanalysis of specimens prepared by polishing and etching reveals significant compositional inhomogeneities. |
