【 摘 要 】

In this paper, we will report the Ag-doping effect on the structure and morphology of La08Ca02MnO3 (LCMO) and La075Ag005Ca02MnO3 (LACMO) materials. LCMO and LACMO materials were synthesized via the sol-gel method and sintered at 900 °C for 24h. The structure of the materials was characterized using X-Ray Diffractometer (XRD) and found that both materials are in the orthorhombic structure (Pnma space group). Scanning Electron Microscopy (SEM) was used to observe the morphology of the material and obtained the homogeneity of the materials. With Ag doping, the grain size of the material will decrease. The results of Electron Dispersive Spectroscopy (EDS) confirm the composition of both materials.
