Composite of BaTiO/sub 3/ and Pb(Zr,Ti)O/sub 3/ fabricated with CO/sub 2/ laser

Abstract

A new composite was synthesized by bonding Pb(Zr,Ti)O/sub 3/ with BaTiO/sub 3/ using a CO/sub 2/ laser, Pb(Zr,Ti)O/sub 3/ was the thick film (0.05 mm in thickness) and BaTiO/sub 3/ was the sintered body, fabricated by the conventional method. The CO/sub 2/ laser was 143 W/cm/sup 2/, and the irradiation continued for 50 s. The two starting materials were bonded, and Pb(Zr,Ti)O/sub 3/ was evaluated by an XRD (X-ray diffraction) analysis. The interfaces between the two ceramics were examined. Results of electron probe microanalysis (EPMA) and electric properties are discussed.<>
