Bismuth germanate films prepared by Pechini method

Optical Materials, 2010
Abstract Bismuth germanate films were prepared by dip coating and spin coating techniques and the dependence of the luminescent properties of the samples on the resin viscosity and deposition technique was investigated. The resin used for the preparation of the films was obtained via Pechini method, employing the precursors Bi2O3 and GeO2.

Synthesis of CeNb3O9 perovskite by Pechini method

Materials Letters, 2018
Abstract Pechini method was applied for the first time to synthesize CeNb3O9 perovskite at different calcination temperatures (600, 800 and 1000 °C). A solution of water, citric acid, ethylene glycol, ammonium niobium oxalate and cerium ions was polymerized and calcined at 300 °C for 2 h.

Effect of calcium doping on LaCoO3 prepared by Pechini method

Powder Technology, 2013
Abstract Calcium doped lanthanum cobaltite (La1 − xCaxCoO3) (x = 0, 0.2, 0.4, 0.6, 0.8) with different concentrations has been prepared by modified Pechini type polymerizable method. The X-ray diffraction pattern of the calcium doped samples shows the formation of perovskite material in cubic structure.

The Preparation of BaCeO3 Nanopowders by Pechini Method

Proceedings of the 2019 The 2nd International Conference on Robotics, Control and Automation Engineering, 2019
BaCeO3 Perovskite-type oxide single phase nanopowders were prepared by the Pechini method. A polymeric precursor was synthesized by use of Ba(NO3)2 and Ce(NO3)3•6H2O AR powders as metal ion sources, and citric acid and ethylene glycol as chelating agents and reaction medium, respectively.

Preparation of nanocrystalline ferroelectric BaBi4Ti4O15 by Pechini method

Materials Letters, 2006
A gel was formed when an aqueous solution of BaCl2, BiNO3, TiOCl2 and citric acid in stoichiometric ratio is heated on a water bath. This gel on decomposition at 600 °C produced the nano crystallites of ternary oxide, BaBi4Ti4O15 (BBT). The phase contents and lattice parameters were studied by the powder X-ray diffraction (XRD).
