| Abstract: | In this paper Ca3Co4O9 ceramics were fabricated by solid reaction method, and the appropriate fabrication technologies were fixed. The microstructure and crystal composition of the samples were characterized by using XRD,SEM and EDX.It showed that Ca3Co4O9 ceramics contained randomly-oriented plate-shaped grains with layered structure, and appropriate sinter temperature and holding time made for the growth of the organization. |
