The formation of perovskite PbTiO3 powders by sol-gel process
Nano-sized cubic Pb2Ti2O6 and monoclinic PbTi3O7 were obtained as the first stage products, by sol-gel process using anhydrous lead acetate and titanium(IV) isopropoxide as precursors; then, as the powder was heated, Pb2Ti2O6 gradually transformed to perovskite PbTiO3 around 673 K.
