Modified Pechini Processing of Barium and Lanthanum-Lithium Titanate Nanoparticles and Thin Films.

Barium-strontium titanate (BST) BaSr TiO and lanthanum-lithium titanate (LLT) LaLiTiO nanopowders and thin films have been obtained via the modified Pechini route. Polyesterification and complexation processes of gel formation have been examined. Hypothetical models of coordinative polymers formed in sol-gel system have been suggested.
