Seeding of PMN powders made by the Pechini method
(Elsevier B.V., 2001-01-01)
The partial oxalate method, with the columbite route, associated with the Pechini method, was used to obtain a very fine ceramic powder at low temperature. Using this route it was possible to obtain a very reactive powder ...
Synthesis of nanocrystalline tetragonal zirconia by a polymeric organometallic method
(Wiley-Blackwell, 1999-07-01)
A polymeric precursor method based on the Pechini process was successfully used to synthesize zirconia-12 mol% ceria ceramic powders, the influence of the main process variables (citric acid-ethylene glycol ratio, citric ...
Europium(III)-containing zinc oxide from Pechini method
(Elsevier B.V., 2002-10-07)
ZnO:Eu3+ (0.1 and 3 at%) with average particle size of 500 nm were prepared by the Pechini method. Photoluminescence spectroscopy evidences that there is no energy transfer between ZnO and Eu3+ ion. The emission spectrum ...
New methodology for a faster synthesis of SrSnO3 by the modified Pechini method
(2013-04-01)
SrSnO3, a perovskite-type complex oxide, was synthesized by the modified Pechini method using two different precursors, tin chloride and metallic tin. The first one is already traditional in the literature and it claims ...
Influence of the network former on the properties of magnesium spinels
(Springer, 2007-03-01)
Undoped and/or doped with 1 mol% of Co2+ Mg2TiO4 and Mg2SnO4 powders were synthesized by the polymeric precursor method. The influence of the network former (Sn4+ or Ti4+) on the thermal, structural and optical properties ...
Métodos químicos para obtener varistores basados en SnO2
(2006-11-01)
Synthesis of SnO2 ceramic powders was made by coprecipitation method and polymeric precursor method (Pechini) to obtain Sn-Co-Nb-Ti-Al varistor systems. The particles of the obtained ceramic powder presented nanometric ...
LiNbO3 thin films prepared from a polymeric precursor method
(1997-12-01)
LiNbO3 thin films were prepared from polymeric precursor method by dip coating. The precursor films, deposited on Si(111) substrates, were heat-treated from 400°C to 900°C in order to study the heat treatment influence on ...
Influência da adição de níquel na síntese do SrSnO3
(Associação Brasileira de Cerâmica, 2008-03-01)
Pós cerâmicos microestruturados de Sr1-xNi xSnO3 (x de 0 a 0,20) foram sintetizados com sucesso pelo método dos precursores poliméricos. Os precursores foram caracterizados por análise térmica. Três etapas de decomposição ...
Indium tin oxide films prepared via wet chemical route
(Elsevier B.V., 2007-12-03)
In this work, indium tin oxide (ITO) films were prepared using a wet chemical route, the Pechini method. This consists of a polyesterification reaction between an alpha-hydroxicarboxylate complex (indium citrate and tin ...
Synthesis and sintering of ZrO2-CeO2 powder by use of polymeric precursor based on Pechini process
(Kluwer Academic Publ, 2001-01-01)
Nanocrystalline ZrO2-12 mol % CeO2 powders were synthesized using a polymeric precursor method based on the Pechini process. X-ray diffraction (XRD) patterns showed that the method was effective to synthesize tetragonal ...
