Abstract

Silica particles occupy noticeable position among metal oxide particle, because of their simple preparation and wide uses such as catalysts, electronic and thin film substrates electrical and thermal in insulators, humidity sensors, emulsifiers, stabilizers, etc. Silica Nano particles use as filler to reinforce the rubber, polymer and also concrete. Recently in experimental studies of preparation of silica particle, it's often desirable to produce particle, which are spherical and uniform size. Such monodispersed particles yield results which are not influenced by shape and size distribution effects. The process of NANOSILICA formation in the reaction of PRECIPITATION from solution of sodium silicate and sulfuric acid has been studied. SODIUM DODECYL SULFATE (SDS) and POLYVINYLPYRROLIDONE (PVP) were used as surfactant. Optimum parameters of the PRECIPITATION were undertaken. Principal physicochemical properties of the silica were tested, including particle shape, PARTICLE SIZE and morphology. X-ray diffraction (XRD), scanning electron microscope (SEM), transmission electron microscope (TEM) have been used for the Characterizations of the produced nano silica. The result shows that using SDS and POLYVINYLPYRROLIDONE (PVP) in process have changed the properties of precipitated silica.
