Production of Silica Particles by Electrostatic Atomization [Translated]†
Electrostatic atomization is a method typically used to produce fine liquid droplets with diameters between ten and several hundred micrometers and a relatively narrow size distribution. This method is simple but its mechanism is not yet fully understood.Our research involved producing fine silica particles by forming droplets of water glass no. 3 using electrostatic atomization, then dehydrating them and removing their sodium ions. The atomization state was classified into three modes according to applied voltage: dripping, uniform cone-jet, and discharge modes. Uniformly sized droplets were produced only with the uniform cone-jet mode at a positive high voltage. The mean volume diameter of silica particles could be estimated as a function of flow rate and applied voltage, as well as the surface tension, viscosity, and conductivity of the water glass solution.† This report was originally printed in J. Soc. Powder Technology, Japan. 38(2), 90-96 (2001) in Japanese, before being translated into English by KONA Editorial Committee with the permission of the editorial committee of the Soc.
