In this poster, we present the techniques to synthesize CaFe2O4 nanoparticles using auto-combustion
and co-precipitation methods. The influence of both synthesis method on the resulted particle size and
magnetic property of the CaFe2O4 nanoparticles were compared and investigated. In the co-precipitation
method, sodium hydroxide (NaOH) is used as catalysis. In addition, the sample dried in the oven at 80°C
overnight then the CaFe2O4 powder was obtained. In case of auto-combustion method in the beginning, can
observed the sol form then slowly converting to gel then burnt at 250°C then the final nanoparticle calcined
at 550°C. The difference in synthesis method results in different physical property and magnetic property.
The XRD results show that the nanocrystals contain various phases with orthorhombic crystal structures for
both processes. For sample synthesized using a co-precipitation method, the particle size was about 10.8 nm
which is smaller than that using auto-combustion method. The magnetic saturation Ms of CaFe2O4 for sample
synthesized using co-precipitation method were 47.279emu/g, which is higher than that of the autocombustion method where the Ms of 31.10emu/g was measured while the value of Hc was 17.380 G, and
6.1672 G, respectively. The synthesized paramagnetic particles is believed to have potential application in
targeted drug delivery system
