Analysis of Ca-PZT powder obtained by the Pechini and partial oxalate methods
(Associação Brasileira de Cerâmica, 2008-03-01)
Pós de Ca-Pb(Zr,Ti)O3 (Ca-PZT) foram preparados por um método combinado que consiste na técnica Pechini para as partículas intermediárias de ZrTiO4 (ZT) e a rota do oxalato para o pó final. Os produtos intermediário e final ...
Synthesis of nanocrystalline tetragonal zirconia by a polymeric organometallic method
(1999-01-01)
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 ...
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 ...
Respuesta eléctrica de películas gruesas del sistema SnO2-TiO2, conformadas con polvos cerámicos obtenidos a través del método pechini
(2007-11-01)
Tin oxide is the compound more used in the gas sensor production, mainly to reduce gases like CO and H2. Their electrical properties are strongly dependent of its surface. For this is of great importance to synthesize ...
