Abstract :

The CuNiCA nanopanicles have been synthesized by sol-gel auto-combusson. microwave and co-precipitationtechniques. Then, the results of the three techniques were compared. In the vol-ael auto-combustion synthesiswas used glycine as a fuel. At first, sol was prepared. Then, gel was achieved from drying so'. The prepared gelwas burnt at 350°C. In the noicrowavc technique, gel was prepared. Then, the final nanoparticles were producedon influence of microwave irradiation. The CuNiO2 nanoparticles 'ere prepared by co-pAcipitation methodinvolved metal sulfates The temperature of calcmations was 620T. These minoparticles were investigated byX-ray diffraction (XRD) and Scanning Plectmn Microscopy (SEM) techniques. The XRD results show that thenangeryssil eon tat iis various phases. stnictures and the average size of MilliThIMCIIMA CuNi0: cry stallities wascalculated by Scherer equation. Scanning Electron Microscopy was also used to characterize the microstnic tareand morphology.
