PTCa/PEEK composite acoustic emission sensors
(2006-10-01)
Composites made of Calcium-modified lead titanate (PTCa) and poly (ether-etherketone) (PEEK) high performance polymer matrix were prepared in the film form using a hot press. The ceramic volume fraction reaches up to 60 ...
Calcium modified lead titanate/poly-ether-ether-ketone composite for acoustic emission sensors
(2005-12-01)
Composites made of calcium modified lead titanate ceramic powder and poly (ether-ether-ketone) high performance polymer matrix were prepared in the film form using a hot press. The acoustic and electromechanical properties ...
Dielectric and ferroelectric properties of PZT and PT thin films for saw sensors applications
(2004-12-01)
It is very important for the building of the SAW devices to study dielectric and ferroelectrics properties because every SAW device is based in piezoelectric effect that it is made up to transform an electric sign in the ...
Synthesis and sintering of PZT ceramics
(Kluwer Academic/plenum Publ, 1999-01-01)
Lead zirconate powder, with Zr/Ti ratio of 50/50 was prepared by polymeric precursor method and doped with 3, 5 and 7 mol% of Sr+2 Or Ba+2, as well as by 0.2 to 5 mol% of Nb+5. The powder was calcined at 750 degrees C by ...
Structural effects on perovskite phase formation for pzt powders obtained by polymeric precursor method
(2018-01-01)
Many synthesis methods are available to obtain a set of specific characteristics for lead zirconate titanate (PZT) piezoelectric ceramic powders. In this work, we have successfully prepared PZT powder samples through the ...
