Lanthanum modified lead zirconate titanate have been prepared using sol-gd route. Inorganic salts metal alkoxides lead acerate (Pb(C2H3O2)(2)).3H(2)O, tetrabutyl titanate (Ti(OC4H9)(4)), lanthanum nitrate (La(NO3)(3) . 10H(2)O), and zirconium oxide nitrate (ZrO(NO3)(2)) were used as starting materials. Acetylacetone was used as chelating agent and formamide was used as drying control chemical additive (DCCA). Crack-free films were obtained. X-ray diffraction measurements indicated that the crystal constant of PLZT samples changes with sintering temperatures. The additive of formamide can control the hydrolysis rate and improve the surface morphology.
