Abstract
A method of applying a castable refractory composition using a form. The refractory composition consists essentially of from about 50.0 weight percent to about 99.9 weight percent of a high purity silicon dioxide and from about 0.1 weight percent to about 30.0 weight percent of a potassium silicate binder. About 0.1 weight percent to about 30 weight percent water based upon 100 weight percent of the refractory composition may be added to achieve a pumpable consistency of the refractory composition.
