Abstract

Abstract MgO – TiB2 nanocomposite was synthesized using mixtures of TiO2, H3BO3 and Mg as raw materials via a mechanochemical process. The phase transformation and structural evaluation were investigated by means of X-ray diffractometry, scanning electron microscopy, transmission electron microscopy and differential thermal analysis techniques. Thermodynamics evaluations indicated the reaction was highly exothermic and should be a mechanically induced self-sustaining reaction. According to X-ray analysis, MgO – TiB2 nanocomposite was formed after 4 h of ball milling. Thermal analysis results revealed that after 3 h milling, the temperature of combustion reaction decreased and all the reactions happened simultaneously. Scanning and transmission electron microscopy observations confirmed the range of particle size was within 100 nm.
