Facile and economic method for preparation of nano-colloidal Silica with controlled size and stability
This study is focused on synthesis of nano-colloidal silica via alkaline water glass solution. Sodium ions of water glass were removed by cation exchanging in a resin column to obtain the silicic acid which was titrated to the solution of sodium silicate. Concentration of the colloidal silica and pH value of the solutions were controlled using different concentrations of alkaline sodium silicat...

متن کاملDispersion stability and drying behavior of colloidal silica
Colloidal suspensions containing nano-sized particles are used in numerous applications such as batteries, inks and paints, and also used as precursors to a wide variety of industrial materials. The ability to control the microstructure during drying is important for many potential applications. When it comes to solar cell technology, controlling the microstructure plays a critical role ranging...
متن کاملStability of Penicillin G in Oleaginous Formulations Containing Colloidal Silica
Stability or procaine and potassium salts of penicillin G in oleaginous Materials containing colloidal silica was studisd. The instability of penicillin G in these bases seeMed to be due pr!Marily to the surface acidity or the silica in conjunction with the ester constituents of oils. The stability or the peanut oil/silica/ penicillin G preparations could be !Mproved by reducing the surface aci...
متن کاملSynthesis of colloidal silica dumbbells.
We describe the synthesis and characterization of stable suspensions of monodisperse fluorescently labeled silica dumbbell particles. Pure dispersions of silica dumbbells with center-to-center lengths from 174 nm to 2.3 microm were produced with a variety of aspect ratios. Individual particles in concentrated dispersions of these particles could be imaged with confocal microscopy. These particl...
