EN The mechanical and electrical properties in lanthanum modified lead zirconatetitanate ceramics of 5/50/50 and 10/50/50 were studied by mechanical loss Q-1, Young’s modulus E, electric permittivity epsilon and tangent of dielectric loss of angle tg delta measurements. The internal friction Q-1 and Young modulus E measured from 290 K to 600 K shows that Curie temperature TC is located at 574 K and 435 K (1st cycle of heating) respectively for ceramic samples 5/50/50 and 10/50/50. The movement of TC in second cycle of heating to lower temperature (561 K for 5/50/50 and 420 K for 10/50/50) has been observed. Together with Q-1 and E measurements, temperature dependences of epsilon=f(T) and tg delta=f(T) were determinated in temperature range from 300 K to 730 K. The values of TC obtained during epsilon and tg delta measurements were respectively: 560 K for 5/50/50 and 419 K for 10/50/50. These temperatures are almost as high as the temperatures obtained by internal friction Q-1 measurements in second cycle of heating. In ceramic sample 10/50/50 the additional maximum on internal friction Q-1 curve at the temperature 316 K was observed.
