Highly uniform Fe3O4 and Co3O4 microspheres were successfully synthesized.
The Tc of AP with 1, 2, 4 and 8 wt% of Fe3O4 microspheres was decreased by 58, 80, 102 and 129 °C.
The Tc of AP with 1, 2, 4 and 8 wt% of Co3O4 microspheres was decreased by 55, 74, 112 and 131 °C.
The thermal decomposition process of AP was detected by TG-IR.
