Abstract: Submicron sized boric acid particles are used in traditional lubrication oils as they provide a low friction coefficient and they are friendly to the environment. In the present study, size and structure changes in high energy ball wet milled boric acid particles were investigated and characterized by X-ray diffraction (XRD), BET, and thermo-gravimetric/differential thermal analysis (TG-DTA). It was seen that increasing time of milling resulted in smaller particle formation and a larger specific surface area. Moreover, it appeared that thermal decomposition temperatures were not size dependent.
