LIGHTWEIGHT REFRACTORY CASTING COMPOSITION AND ARTICLES MADE USING FOAMED COLLOIDAL SILICA BINDER
A porous refractory composition containing a foamed colloidal silica binder, and porous refractory articles made from it, are provided. The foamed colloidal silica binder has a total porosity of about 50% to about 95% by volume and includes a synthetic, non-protein foaming agent mixed with colloidal silica and water. The foamed colloidal silica binder has sufficient durability and integrity to withstand the mixing with dry refractory ingredients to form a porous refractory composition, casting the refractory composition into a refractory shape, and drying the shape to form a porous refractory article having a porosity of about 25% to about 75% by volume. The resulting refractory articles have excellent high-temperature durability and insulating properties.
