摘要：
We present dielectric studies carried out on PbK2LiNb5O15 exhibiting its ferroelectric behaviour: the rea art of dielectric constant follows a Curie law, with T-c approximate to 639 K and a Curie constant 1.5x10(5) K. The structural change involves a first order phase transition evidenced by a thermal hysteresis and a epsilon(r)' discontinuity, and also an intermediate phase. An ionic conductivity, probably related with the Li+ ion mobility, is also evidenced.
