摘要：
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. (C) 1999 Elsevier Science B.V. All rights reserved.
