Influence of silver (Ag) doping on a crystal structure of La0.7Ag0.1Ca0.2MnO3 and La0.65Ag0.15Ca0.2MnO3 manganites synthesized by sol-gel method

Perovskite manganite material has been extensively investigated because it has many attractive properties. In this paper, crystal structure of La0.7Ag0.1Ca0.2MnO3 (LACMO1) and La0.65Ag0.15Ca0.2MnO3 (LACMO15) materials will be reported. LACMO1 and LACMO15 materials were synthesized by sol-gel method...

Description
Summary:Perovskite manganite material has been extensively investigated because it has many attractive properties. In this paper, crystal structure of La0.7Ag0.1Ca0.2MnO3 (LACMO1) and La0.65Ag0.15Ca0.2MnO3 (LACMO15) materials will be reported. LACMO1 and LACMO15 materials were synthesized by sol-gel method with sintering temperature 900°C for 24h. Structural properties of LACMO1 and LACMO15 materials were characterized using X-Ray Diffractometer (XRD). The characterized results show a crystal structure transition from orthorhombic (Pnma spacegroup) to rhombohedral (R3¯c space group) along with increasing the concentration of Ag doping. The crystal structure transition show there is a distortion of the material structure caused by Ag-doping. Increasing the concentration of Ag doping may affect the tolerance factor (t) that used to measure the degree of distortion of a perovskite.
