Abstract
Improved inorganic ceramic papers comprising heterogeneous grades of ceramic fibers, namely small, high surface area fibers and at least one larger, lower surface area ceramic fiber are bonded into a matrix with the aid of an inorganic binder system having at least one metal oxide with an average particle size below 200 nm. Multiple different grades of inorganic ceramic fibers and small particle size inorganic binders impart good tensile strength and flexibility characteristics in the same sheet.
