THE REACTION BETWEEN AMMONIUM OXALATE AND IODINE
The reaction between ammonium oxalate and iodine has been studied both in light and in dark: The results obtained are similar to those obtained in the case of potassium oxalate and iodine. Thus, in dark the reaction is unimolecular with respect to iodine and ammonium oxalate. but becomes semi-molecular with respect to iodine in light.

Ammonium oxalate-assisted synthesis of Gd2O3 nanopowders
The impacts of co-precipitation reaction temperature and duration, as well as calcination temperature and duration, on the particle morphology and properties of gadolinia (Gd2O3) nanopowders were investigated. Thermogravimetric curve of thermally treated gadolinium oxalate (Gd2(C2O4)3) showed that pure stable cubic phase Gd2O3 nanopowders could be ...
