Induction plasma synthesis of nanometric spheroidized glass powder for use in cementitious materials

► Synthesis of nano-spheroidized glass powder (NSGP) using an induction plasma torch. ► Explanation of the vaporization, nucleation and growth mechanisms of NSGP. ► Morphology, size, % NSGP and chemical composition characterization versus the plasma conditions. ► Plasma chemistry and thermodynamic for the nucleation and coalescence conditions.
