✦ Synopsis

Pb(Znl/3Nb2/a)O3 thick films with the perovskite structure were prepared by the sol-gel method. Niobium ethoxide Nb(OC2Hs)4, lead acetate Pb(CH3COO)2, and Zinc 2ethylhexanoate Zn(O2CsH15)2 were reacted in 2-methoxyethanol to form the precursor. Titanium isopropoxide, Ti(O.i-C3HT)4 and barium isopropoxide Ba(O.i-C3HT)4 were added into the precursor solution to stabilize the formation of the perovskite phase. Films of upto 10 gm thickness were obtained by controlling the viscosity of the solution and the dipping speed of silicon wafers. The phase evolution was investigated using differential thermal analysis (DTA) and X-ray diffraction techniques. The thickness-dependent dielectric constant of the resultant films is also reported.

The role of the La-addition on the A-site of the perovskite Pb(Mg 1/3 Nb 2/3 )O 3 (PMN) on the phase formation, microstructure and dielectric properties was investigated. Ceramic samples were obtained from PMN and (Pb 1-x La x )(Mg 1+x/3 Nb 2-x/3 )O 3 (PLMN) nanopowders synthesized by the columbite
