Lanthanum‐doped Ba 0.6 Sr 0.4 4TiO (OH) 2 C 2 O 4 .4H 2 O was prepared by precipitation from a pH‐controlled oxalic acid solution for conversion to the titanate. TGA and DTA support the proposed formula of a hydrated, mixed hydroxyoxalate. Density and resistivity measurements of the titanates are correlated as a function of lanthanum content.
