= METHOD OF MAKING LIGHTWEIGHT REFRACTORY COMPOSITION AND ARTICLES USING FOAMED COLLOIDAL SILICA BINDER =

'''Abstract''':
a foamed colloidal silica binder having a total porosity of about 50% to about 95% by volume can be used to make porous refractory compositions and refractory articles having a porosity of about 25% to about 75% by volume. the foamed colloidal silica binder endures mixing with refractory ingredients to form the porous refractory composition, casting the refractory composition into a refractory shape, and drying the shape to form to refractory article, without significant collapsing of the foam. the resulting lightweight refractory articles are useful in a wide variety of insulating and weight-reducing applications.
