Abstract

In this study, SiO₂ nanoparticles were synthesized by an eco-friendly method, which excludes harmful elements, such as NO ₃^-, and in so doing, lowers the heat-treatment temperature from 500 to 300 °C, leading to the downsizing of the nanoparticles. The sizes of the SiO₂ nanoparticles were less than 20 nm and were uniformly distributed. In the XRD analysis, the most intense peak was observed at about 23.5° confirming that the synthesized nanoparticles have a SiO ₂ structure. No harmful elements such as NO₃^- were found in the SiO₂ nanoparticles, showing that their purity was improved. Also, SiO₂ paste was well formulated by dispersing the SiO₂ nanoparticles uniformly in a solvent uniformly. The SiO ₂ paste printed onto a glass substrate followed by curing at 200 °C showed good insulating and dielectric properties. The resistance and the dielectric constant of the printed layer were above 10¹¹ Ω and 4.434, respectively. Those values were sufficient for insulating and dielectric characteristics. Therefore, the SiO₂ nanoparticles synthesized by this eco-friendly method have the potential to be used as the material for insulating and dielectric layers.
