Óxido de zinco dopado com gálio preparado pelo método Pechini
(Editora Unesp, 2002-01-01)
Óxido de zinco dopado com gálio (ZnO:Ga) foi preparado pelo método Pechini a partir de citrato de zinco e hidróxido de gálio. Utilizsando este método, foi possível obter ZnO:Ga cristalino pela calcinação do precursor ...
Gallium-doped zinc oxide prepared by the Pechini method.
(Editora Unesp, 2002-01-01)
Gallium-doped zinc oxide (ZnO:Ga) was prepared by the Pechini method from zinc citrate and gallium hydroxide. By this method, it is possible to synthesize crystalline ZnO:Ga by firing the polymeric precursor in air at ...
Influência do oxalato de amônio na formação do precursor columbita obtido pelo método Pechini
(Associação Brasileira de Cerâmica, 1999-06-01)
A rota da columbita para síntese do PMN (Pb3MgNb2O9) é um processo que permite reduzir significativamente a formação de fases secundárias. O método Pechini, utilizado na síntese da columbita, permite perfeita homogeneidade ...
A comparison between neodymium doped alumina samples obtained by Pechini and sol-gel methods using thermo-stimulated luminescence and SEM
(ELSEVIER SCIENCE BV, 2010)
Neodymium doped and undoped aluminum oxide samples were obtained using two different techniques: Pechini and sol-gel. Fine grained powders were produced using both procedures, which were analyzed using Scanning Electron ...
The influence of the synthesis route on the final properties of SnO2-based varistors
(Elsevier B.V., 2008-04-01)
A comparative study of two customary routes of ceramics processing applied to the synthesis of SnO2-based varistors is reported in this paper. Devices of equivalent composition were prepared through the Pechini method and ...
Bismuth germanate films prepared by Pechini method
(ELSEVIER SCIENCE BV, 2010)
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 ...
Estudio de PMN cerámico dopado con KNbO3 y LiNbO 3 sintetizado por Pechini
(2002-12-01)
PMN belongs to a special class of materials named relaxor ferroelectrics. It has high volumetric efficiency due to its high dielectric constant, which makes it in a perfect material for application in multilayer capacitors. ...
Synthesis and characterization of PLZT (9/65/35) by the Pechini method and partial oxalate
(Elsevier B.V., 1998-05-01)
ZrTiO4 (ZT), obtained by the Pechini method, was used as precursor for obtaining PLZT (lead lanthanum zirconium titanate). An aqueous solution of oxalic acid was prepared with particles of ZT, Pb(NO3)(2) and La2O3. After ...
Influence of the concentration of Sb2O3 and the viscosity of the precursor solution on the electrical and optical properties of SnO2 thin films produced by the Pechini method
(Elsevier B.V., 2002-02-22)
SnO2:Sb multi-layer coatings were prepared by the Pechini method. An investigation was made of the influence of the concentration of Sb2O3 and the viscosity of the precursor solution on the electrical and optical properties ...
Structural and microstructural analyses on Sm-modified BaTiO3 obtained from the Pechini's method
(Taylor & Francis Ltd, 2018-01-01)
Barium titanate (BaTiO3) ceramics, prepared by the Pechini's method, were investigated considering the influence of the samarium-modifier concentration. Nanosized crystallites in the order of 15-20nm have been successfully ...
