  • A colorless, high-purity form of silica is called fumed silica.
  • Fumed silica is an enterosorbent, i.e. an agent that absorbs and removes substances harmful and toxic to the body from intestinal tract.
  • Fumed silica has a chain-like particle morphology.
  • Fumed silica is composed of submicron-sized spheres, which are 40-60% fused into short chains, very highly branched, 0.1-0.2 microns long.
  • Fumed silica is manufactured by a similar flame hydrolysis process to synthetic fused silica.
  • One production method for the production of fumed silica involved a continuous flame hydrolysis technique.
  • Fumed silica (FS) particles are dispersed in different oligoethers and in high-molecular weight poly(ethylene oxide) PEO and their properties evaluated with the aim to fine tune them for improved performance.
  • Fumed silica is prepared by the flame hydrolysis of silicon tetrachlot-ide (Sit&) in a flame of Hz and 02.
  • Synthesis of non-agglomerated, spherical fumed silica particles in a flame aerosol reactor using laminar and turbulent classic and double diffusion flames has been studied.
  • Suspensions of fumed silica in polypropylene glycol exhibit diffraction to elucidate microstructural changes that occur
    shear-thickening under steady shear and ‘‘strain-thickening’’ un- during shear-thickening (1, 2). He concluded that the incipider
    oscillatory shear.
  • Fumed silica is used on large scale in the production of toothpaste. It keeps teeth enamel safe providing excellent polish and serves as a carrier of active ingredients in gel toothpaste.
  • Fumed silica functions as a stabiliser and anti-settling agent of pigments and as an anti-sedimentation additive.
    Fumed silica is active reinforcing filler used in the production of silicon rubbers.
  • Fumed silica have been used commercially in a wide range of applications to enhance viscosity of many liquids, including paints. The most common application in biochemistry is for clarifying sera by removing lipids.
  • The addition of fumed silica and hydroxy apatite in Radiation Vulcanized Natural Rubber Latex(RVNRL) improves tear strength and aging properties of rubber films, whereas tensile strength and degradability of rubber films were unchanged during storage at room temperature.
  • The structure of nanometer sized silica particles called fumed silica, which can be produce by burning silicon tetrachloride in an oxygen-hydrogen flame using infrared and raman spectroscopies and high energy x-diffraction technique.
