Abstract :
Nanosized La1-xCuxMnO3 (x≤0.1) was synthesized at different temperatures by using heteronuclear complexing method. X-ray diffraction analysis show that sample consists of two phases: La1-xCuxMnO3 (x≤0.1) having R3̅c space group with rhombohedral symmetrical structure and La2Cu2O5 having C2/c space group with monoclinic symmetrical structure. The results show the quantity of La1-xCuxMnO3 increase from 91.22 to 97.62%, while quantity of La2Cu2O5 compound decrease from 8.78 to 2.37% with rising of calcination temperature from 500°C to 900°C. The Photon Cross Correlation Spectroscopy (PCCS) was used to measure size distribution. The results reveal that particle mean diameter increases from (276±4) to (455±5)nm, particle specific surface area (Sv) decreases from 21.84 to 13.29 m2/cm3, particle size distribution equals to 55-761nm and particle surface and volume mean diameter (SMD, VMD) increase from 247 to 459nm.
