New synthetic route in obtaining copper chromite I. Hydrolysis of some soluble salts
The possibility of obtaining copper chromite through thermal decomposition of some polynuclear coordination compounds. [Cr2Cu(NH3)(2)(OH)(6)](NO3)(2) and [Cr2Cu(OH)(8)]. 4H(2)O obtained through hydrolytic decomposition of chromium and copper soluble salts was considered. A decomposition mechanism of the pattern compounds is proposed. A pure tetragonal Cr2CuO4 with mean crystallite sizes varying in the range 133-210 Angstrom was obtained between the temperature limits 823 K-1073 K.
