摘要：

The RF thermal plasma synthesis route was used for the preparation of alumo-silicate spherical particles. Homogeneous solid mixtures of raw materials (Al2O3, SiO2 and KOH) were used as precursors. SiO2 powders with different particle sizes (6 mu m and 40 mu m) were taken for this synthesis. For the characterization of obtained materials: scanning electron microscopy (SEM), transmission electron microscopy (TEM). X-ray powder diffraction (XRD) analysis, infrared spectroscopy (FTIR) and thermogravimetric analysis (TG/DTA) were used. Nanosized amorphous ceramic particles were formed via two-step RF thermal plasma processing. It was demonstrated that the size of the SiO2 particles plays a significant role in the formation of the alumo-silicate nanoparticles. (C) 2012 Elsevier B.V. All rights reserved.
