An economical and environmentally friendly method for preparing silica nanoparticles has been proposed. Use sol-gel with ultrasound to prepare SiO2 NPs at the temperature of 400 °C and a time of 1 hour. Silica particles were obtained by hydrolysis of tetraethyl silicate (TEOS) in ethanol medium and a detailed analysis of the effect of particle sizes was performed. Different sized particles were synthesized in the range of 30 nm. Scanning electron microscopy, Atomic Force Microscopy (AFM) and was applied to study particle size. The influence of the temperature on particle size has been studied possibly used in drug delivery, supercapacity and Used as an electrically insulating material in nanoelectrical. The results obtained in this study are in line with the results found by literature studies.
