Abstract

Abstract The polycrystalline samples of Pb 5− x La 1+ x Ti 3+ x Nb 7− x O 30 ( x=0,1,2) complex tungsten–bronze type were prepared by a high-temperature solid-state technique. X-ray diffraction (XRD) study suggests the formation of single phase compounds in an orthorhombic structure at room temperature. Detailed studies of dielectric constant ( ϵ) and dielectric loss ( tan δ) of the above compounds as a function of temperature (−150 to 350 °C) at 10 kHz exhibit a ferroelectric phase transition of diffuse type. Temperature variation of resistivity show that these compounds have negative temperature coefficient of resistance (NTCR) at high temperature.
