Chemical co-precipitation and hydrothermal techniques are used to make magnetic manganese ferrite powder from chemical compounds in the chlorides of manganese and iron and Sodium hydroxide (NaOH) is used as precipitant agent. The calcinations were done at a temperature of 700°C for 6 hours. Through X-ray diffractometer (XRD) and a scanning electron microscope (SEM) with Energy Dispersive X-ray Spectroscopy (EDXS), the structure of a sample that had been prepared for the study was found (EDAX). The chemical bonds in spinel ferrites were found and confirmed with the help of IR absorption spectra.
