Abstract

In this study calcium ferrite nanoparticles are synthesized using a sol-gel method and the magnetic properties of these nanoparticles are characterized. The influence of process parameters, namely molar ratio of starting materials, calcination temperature and effect of polyvinylalcohol (PVA) on particles size is also investigated. These parameters are also necessary to produce nano-sized calcium ferrite particles with a superparamagnetic behavior for drug delivery systems. In the synthesis a PVA polymer is initially mixed with calcium nitrate and ferric nitrate by using a magnetic stirrer. Citric acid is then used to increase the chelation to produce calcium ferrite nanoparticles. The prepared samples are calcined at 550 °C for 2 h in a vacuum oven, and a furnace. The morphological features of the calcium ferrite nanoparticles examined using scanning electron microscopy. The structure and magnetic properties of these materials are also characterized through X-ray diffraction and vibrating sample magnetometry. SEM images reveal spherical calcium ferrite nanoparticles. These nanoparticles also exhibit an orthorhombic structure with a crystal size of 16.8 nm. The magnetic properties of the sample measured using a vibrating sample magnetometer of the sample measured using vibration sample magnetometer are as follows: superparamagnetic with a coercivity of 43.35 G and a magnetic saturation of 59.3 emu/g. This study will contribute to the development of superparamagnetic nanoparticles for targeted drug delivery systems.
