The method entails forming an aqueous slurry of ceramic fiber, cationic starch and silica sol. The silica has, based on total weight of the sol, about 50% silica having a particle size range of from about 7 nm to about 200 nm and a specific surface area of about 100 m2/gm to about 10 m2/gm. The slurry is passed through a porous screen under a vacuum pressure deposit the solids content onto the screen to produce high strength products.
