Modified Pechini synthesis of Bi2ZnB2O7 nanoparticles

Journal of Alloys and Compounds, 2017
Abstract Synthesis of Bi2ZnB2O7 nanoparticles by means of the modified Pechini method is reported. The introduced modifications are based on a proper selection of complexing and polymeric agents, as well as on an optimization of process parameters. The purpose of this optimization was to reduce process duration and temperature.

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.

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.

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.
