Abstract
In this paper, crystal of EuxCa1-xFeyMn1-yO3 (1/4 £ x £ 1/2, 1/4 £ y £ 1/2) has been synthesized with sol-gel method, in which gel is sintered in 750 ºC with muffle furnace and then grounded into powders. The structure of the synthesized EuxCa1-xFeyMn1-yO3 has been studied using X-ray powder diffraction and the results reveal that Eu1/2Ca1/2Fe1/3Mn2/3O3 is well-crystallized. The scanning electron microscope demonstrates that Eu1/2Ca1/2Fe1/3Mn2/3O3 has a similar layer structure and laser particle size analyzer indicates that the particle size is in the range of 0.5-2.5 μ. The thermogravimetric analysis of Eu1/2Ca1/2Fe1/3Mn2/3O3 shows that the material possesses a good thermal stability from 0-900 ºC. The electrical property of Eu1/2Ca1/2Fe1/3Mn2/3O3 has been analyzed with resistance-temperature curve, which suggests that it is an insulator below 300 K.
