INORGANIC FIBER PAPER

PROBLEM TO BE SOLVED: To provide an inorganic fiber paper with its density controlled in a favored range while improving impregnation property before firing. SOLUTION: The inorganic fiber paper is a sheeted substrate obtained by wet type sheet making using a living matter solubility ceramic fiber， a glass fiber with its blending ratio in the fiber content being 0 weight% or over and 70 weight% or under， an organic fiber with an average fiber diameter of 17 μm or over and 25 μm or under， at least one kind or over of a cationic inorganic binder selected from aluminium sulfate， polyaluminum chloride， cationic colloidal silica， and alumina sol， and sepiolite with its blending ratio toward the fiber content being 20 weight% or over and 60 weight% or under.
