Sol-gel synthesis and characterization of Fe(2)O(3) center dot CeO(2) doped with Pr ceramic pigments
(Springer, 2008-07-01)
Undoped x center dot alpha-Fe(2)O(3) y center dot CeO(2) and doped with praseodymium ceramic pigments were obtained by the sol-gel method after heat treatment at 800 degrees C for 2 h. These pigments were characterized by ...
Characterization of nanosized ZnAl2O4 spinel synthesized by the sol-gel method
(Springer, 2009-01-01)
Single-phase zinc aluminate (ZnAl2O4) nanoparticles with the spinel structure was successfully obtained by the sol-gel method. The nanoparticles are crystalline with no impurities related to ZnO or Al2O3 residues. The ...
