Contact SupplierColloidal Silicon Dioxide (Fumed silica) also known as pyrogenic silica because it is produced in a flame, consists of microscopic droplets of amorphous asilica fused into branched, chainlike, three-dimensional secondary particles which then agglomerate into tertiary particles. The resulting powder has an extremely low bulk density and high surface area. Its three-dimensional structure results in viscosity-increasing, thixotropic behavior when used as a thickener or reinforcing filler.
