Advantages of using Gel Bond and Colloidal Silica in
The development of gel bond refractories with colloidal silica as the bonding agent has been a major breakthrough in refractory technology. Since the type of colloidal silica used in refractories is available commercially it became easy for many to take advantage of this technology. In lieu of conventional binders colloidal silica can be used
