Abstract

In the process of producing silica sols by electrodialysis, with porous gas diffusion oxygen cathode instead of steel cathode, the cell voltage can be reduced 0.86～1.13 V,the power consumption of alkali silica sols (pH=9.5) is about cut down 16%, while the current efficiency has no changing. With porous gas diffusion oxygen cathode instead of steel cathode, the electrolysis electrodialysis process can be returned to electrodialysis process.
