المستخلص: CuMn2O4 was synthesized by Solid-State method. MnO2 and CuO were used as precursors. The optimum temperature of synthesis was 850°C. XRD result showed that the prepared compound had a cubic structure with Fd3 m space group. The lattice constant and unit cell volume were a=8.359Å and V=584.14A°3 respectively. The grain size was calculated by the Debye-Scherer method and was 33.49 nm for CuMn204 annealed at 850°C. The experimental density was calculated and compared to the theoretical density. The results were ρt=5.399 gr/cm3 and PE= 5.24 gr/cm3. The electrical properties of the compound showed that it behaves like a semiconductor, and the activation energy of the compound was 0.1535 eV.
