Synthesis of Ca-Fe-O using coprecipitation method employing CaCO 3 and Fe 2 O 3 has been conducted. Extraction of limestone as the raw material of precipitated calcium carbonate (PCC) and iron sands as that of Fe 2 O 3 was prepared to explore various compound of Ca-Fe-O. PCC and Fe 2 O 3 are dissolved in HCl then mixed into homogeneous and precipitated using NH4OH. Mixing is resolved by the mass ratio of PCC and Fe 2 O 3 with a ratio of 1/4, 1/6, 1/8, 1/12. The results of synthesis are sintering at temperature of 700 0 C. The sintered samples were characterized by XRD and SEM-EDX. The results of XRD is indicated the formation of Ca-Fe-O phases that is dominated by Ca 2 Fe 2 O 5 and Ca 2 Fe 9 O 13 phases, and results of SEM/EDX indicate nanoscale particle size that is composed of Ca, Fe, O, and Si elements.
