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.

Modified Pechini synthesis of tricalcium aluminate powder

Materials Characterization, 2012
Abstract Tricalcium aluminate (Ca 3 Al 2 O 6 –C 3 A) was obtained by a modified Pechini synthesis in order to eliminate successive thermal treatments and intermediate grinding usually performed between the two sintering steps and in order to reduce the sintering temperature. Our results indicated that pure C 3 A was obtained, by a single step thermal

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.
