Abstract
Particle synthesis has been performed on perovskite material (La1-xAgx)0.8Ca0,2MnO3 using the sol-gel method. Bulk samples were varied in temperature and time of sintering and doping variations of Ag x=0 and x=0.5. Calculation of stoichiometry was done to get the mass of each precursor. Precursors were included La2O3, AgNO3, Ca(NO3)2.4H2O and Mn(NO3)2.4H2O. Sintering temperature variations were done at 650°C for 5 hours and 900°C for 24 hours. Scanning Electron Microscopy (SEM) was done to see sample morphology with secondary electron mode (SE), homogeneity with backscattered electron mode (BSE) and specify elements contained in the sample with semi-quantitative EDX properties. The SEM-EDX results show the characterization of samples depend on density, porosity, and granular morphology. Microstructures of perovskite materials have a better characterization at doping x=0.5 and at the highest temperature and sintering time.
