Abstract

In the modern electronic field, micron silicon dioxide has unique advantages in electronic packaging due to its low specific surface area, low light scattering, high stability, and low interface reactions. The conventional Stöber and Seed methods are limited by submicron sizes and secondary particles, respectively, hindering the production of micron-sized silica particles in a single step. The continuous drop addition method (CAM) overcomes this limitation by changing the growth state of the particles. In this paper, monodisperse and narrowly distributed silica particles with particle sizes ranging from 0.6 μm to 0.132 μm were obtained by the continuous drop addition method. The roles of tetraethyl orthosilicate (TEOS) addition rate, TEOS concentration and ammonia solution (NH₃·H₂O) volume on the final particle size of silica particles were discussed.
