COLLOIDAL SILICA
SILIFOG®
 
PREFACE
 
Numerous  outlines or surveys of chemistry of silica, especially the water-silica system, have appeared over the past half-century. Properties of silica have been described by Sosman and more recently by Bruchner. The state of knowledge of soluble silicic acid
and colloidal silica was summarized in 1937 by Fricke and Huttig.Ralph K.Iler exhaustively covered the rapidly developing theory and practice of the colloid chemistry of silica and silicates, including new surface chemistry and the role of silica in biology.
The colloidal silica is available for various applications such as fiber, sizing, diazo paper¡¯s manufactures, cellophane film, precision casting, ceramics, glass fiber, paints, catalysts, batteries, wax, optics, elastomer, food, health care, industrial chromatography and polishing.
 
We had have made study of a field of colloid, especially colloidal silica since a few years ago. At the result of development, We¡¯ve SILIFOG® & ACESOL® .
These are colloidal silica consisting of microfine particles of silicon dioxide(SiO2 ) dispersed in water. The particles in SILIFOG® & ACESOL®  are discrete uniform spheres which have no internal surface area or detectable crystalline. Available in grades which vary in particle size, SiO©ücontent, and stabilizing counter ion. SILIFOG® & ACESOL® is formulated with high quality, high purity raw materials.
 
A wide range of today's industrial applications has been developed utilizing of colloidal silica's features. SILIFOG® & ACESOL® are satisfied to their demands.
We¡¯re able to produced the most of colloidal silica¡¯s grades and could control the particles mean characters.
For example particle size, Wt%, viscosity and so on.
In order to manufacture the high quality and purity colloidal products, We¡¯ll do our best now and then. Thank you.
