Preparation of Silica by Sol-Gel Method Using Formamide
In this work we obtained microporous and mesoporous silica gels by sol-gel processing. Tetraethylortosilicate (TEOS) was used as precursor. Nitric acid and hydrofluoric acid were used as catalysts. In order to study the affect of formamide as drying additive, we used a molar ratio alkoxide/formamide of 1/1. The performance of formamide in obtaining crack-free gels was evaluated through monolith...
متن کاملSynthesis and Characterizations of Silica Nanoparticles by a New Sol-Gel Method
Silica nanoparticles were synthesized by chemical methods from tetraethylorthosilicate (TEOS), polyethylene glycol 5% and hydrochloric acid 0.001 N. The sol-gel process was applied for the preparation of nano silica gel. This method is hydrolysis and condensation reactions of TEOS as precursor of silica. The optimal synthesis conditions for the preparation of silica nanoparticles were obtained ...
متن کاملSilica gel-based monoliths prepared by the sol-gel method: facts and figures.
There is a great deal of interest in continuous beds as stationary phases for both HPLC and CEC. There are various ways to prepare monoliths, by polymerization of organic species or by polymerization of silicon alkoxides. The former method has recently been reviewed, while silica based monoliths are now commercially available. The purpose of this paper is to deal with the problems associated wi...
متن کاملPreparation and investigation of magnetic properties of Manganese Cadmium ferrite nanoparticles by Sol-gel method
In the present investigation, manganese ferrite nanoparticles substituted by cadmium with Mn1-xCdxFe2O4 composition and substituted amount x=(0, 0.1, 0.3, 0.5) were prepared by Sol-gel method. Pattern analysis of X-ray diffraction (XRD) confirmed ferrite single phase structure in all samples. The average crystal size was estimated from 17 to 22 nm. The chemical bonds and ferrite formation phase...
متن کاملPREPARATION AND CHARACTERIZATION OF TiO2 Fe2O3 NANOCOMPOSITE BY SOL GEL METHOD
Nanocomposites have improved aspect ratio and better mechanical properties when compared to the composites which had structures less than 100nm They are 1000 times tougher compared to conventional composites. Besides mechanical properties, nanocomposites also have improved electrical conductivity, thermal stability, chemically resistant, flame retardant and low permeability. TiO2 finds its best...
