Dielectric tunability in (1-x)[Pb(Mg 1/3Nb 2/3)O 3]-xPbTiO 3 ceramics for tunable devices application
The dielectric properties of the 0.65[Pb(Mg 1/3Nb 2/3)O 3]-0.35PbTiO 3 ferroelectric ceramic composition were investigated viewing the capability to be used for tunable microwave applications. The dielectric response has ...
Electrical properties of a composite of Polyurethane and ferroelectric ceramics
Ferroelectric ceramic particles based on lead titanate zirconate (PZT) were dispersed in a polymer matrix based on castor oil. After the poling process, the pyroelectric activity of this composite was measured using a ...
The use of pulsed electric acoustic technique for measuring electric field profiles in ferroelectric ceramic
The pulsed electric acoustic technique, PEA, have been usually applied to probe space charge profiles in polymers. In this work we show preliminary results obtained with lead zirconate-titanate and niobium, PZTN, ferroelectric ...
Investigation of the physical properties of PLZT ferroelectric ceramics - Effect of the lanthanum content
In this work, the structural, ferroelectric and dielectric properties, including radio-frequencies and microwave region, has been investigated in Pb1-xLax(ZryTi1-y)1 - (x/4)O3 (PLZT) ferroelectric ceramics, where x = 0.02, ...
Diffuse Effect of the Tungsten Doped Ba(Zr0.10Ti0.90)O3 Ferroelectric Ceramics
Barium zirconate titanate Ba(Ti0.90Zr0.10)O3 ceramics doped with WO<inf>3</inf> (BZT:2W) have been prepared by a traditional solid phase reaction. The effect of temperature on the structural and electrical properties was ...
