摘要: Potassium-modified PLZT [Pb0.92(La1 − zKz)0.08(Zr0.60Ti0.40)0.98 + 0.04zO3 (z = 0.0, 0.1, 0.3, 0.5, 0.7)] ceramics were synthesised using sol-gel technique. Preliminary structural and microstructural parameters determined XRD, SEM TEM techniques. Detailed studies of dielectric properties at 10 kHz in a wide temperature range suggest that the compounds have diffuse phase transition second order. Studies spontaneous polarisation, pyroelectric piezoelectric yielded data for devices.
