Synthesis and characterization of uniform fine particles of copper oxalate

Copper oxalate particles were synthesized in various shapes and sizes by mixing appropriate volumes of known concentration of oxalic acid and copper nitrate at 25 and 85 degrees C. Temperature and reactants concentration had significant effect on the morphology of the precipitated particles and therefore extensive optimizations of the experimental parameters were carried out in order to obtain maximum uniformity in particles' morphological features. Selected batch of the copper oxalate particles was characterized by various physical methods. (C) 2009 Elsevier B.V. All rights reserved.
