Abstract: Microcontroller based thermogravimetric analyser (MTGA) is a home built technique extensively used to study the thermal decomposition of inorganic solids and preparation of nanomaterials. This paper reports the characterization of bismuth ferrite BiFeO3 (BFO) synthesized by microcontroller based thermogravimetric analyser. The synthesized nanopowder is characterized by X-ray diffraction (XRD) method for phase confirmation, crystallite size calculations and scanning electron microscope (SEM) for morphology study. The structure and thermal properties of BFO precursor are studied by using Fourier transform infrared (FTIR) spectroscopy, differential thermal analysis (DTA) and thermogravimetric analysis (TGA). The results of nano BiFeO3 synthesized by microcontroller based TGA are in good agreement with that synthesized by other techniques.
