Purpose: of this study is clearly different synthesis method (microwave method) of non-stoichiometric magnesium iron oxide using in broad area such as high frequency magnets, data storage systems and especially cancer treatment. Design/methodology/approach: Analytically magnesium oxide and iron (III) oxide weighed an appropriate molar ratio and homogenized in an agate mortar. The mixture placed into a porcelain crucible to heat in microwave oven. After the material was exposed to microwave irritation, it was taken from the oven, and then homogenized again. Then, final product was ready to analyse. Powder X-ray Diffractometer (XRD) was used to determine crystal structure of the product. FTIR spectrum was taken to support the functional groups. Thermo gravimetric-differential thermal analysis (TG/DTA) was carried out to identify thermal character. Morphological properties and semi-quantitative analyse of the sample was performed by Scanning electron microscope/ Electron disperse (SEM/EDX). Findings: The XRD patterns show that the product is Mg0.1551Fe1.8966O3 (ICSD 51171). The first time synthesized material is crystallized in hexagonal system with unit cell parameters a=5.0490, b=5.0490, c=13.7890 Å and space group R-3c. The other supporting methods confirm the crystal structure. Non-stoichiometric Mg0.1551Fe1.8966O3 (ICSD 51171) was synthesized by microwave method completely different from literature for the first time. The characterization was mainly based on powder X-ray diffraction pattern. Also, thermal behaviour and morphology were determined. Research limitations/implications: The synthesis method has some disadvantages such as low repeatability, non-uniform product etc. We tried to minimize these negative aspects in our research and succeeded. Practical implications: The compound can be used to reduce side-effects of drugs for cancer treatment, and find broad usage area in that treatment. For his reason, magnesium iron oxide has practical applications. Originality/value: The originality of the paper is first time microwave synthesis of Mg0.1551Fe1.8966O3. In the literature, the magnesium iron oxide was synthesized so many times by different conventional routes. But, as far as we know cheap, clean and short-term synthesis route has not been used before.
