A new, facile preparative route for BaTiO(Ox){sub 2} has been developed (Ox=oxalate). This involves passing a solution of K{sub 2}TiO(Ox){sub 2} through an ion-exchange resin to convert it to the proteo-derivative, H{sub 2}TiO(Ox){sub 2}. Treatment of the latter with BaCl{sub 2} results in precipitation of BaTiO(Ox){sub 2} with a ratio of barium:titanium of 1:1.009. Finally, reaction of BaTiO(Ox){sub 2} with refluxing methoxyacetic acid produces an alcohol and chlorocarbon soluble ceramic precursor that may be used to prepare thin films of barium titanate by metalorganic deposition.
