Un método para tratar haces de fibras inorgánicas duras que comprende abrir una pluralidad de haces de fibras inorgánicas duras de manera que las fibras inorgánicas duras pueden dispersarse en una suspensión líquida para formar un agregado de fibras homogéneas, en el que las fibras inorgánicas duras comprenden el producto de fibrización de 72 a 99 por ciento en peso de alúmina y 1 a 28 por ciento en peso de sílice, en donde dicha abertura comprende alterar mecánicamente las fibras inorgánicas duras y/o haces de fibras, y en donde las fibras inorgánicas duras tienen un volumen de sedimentación por aplastamiento mayor de 250 ml, opcionalmente mayor que 450 ml, y en el que el volumen de asentamiento por aplastamiento se determina de acuerdo con la descripción. A method of treating tough inorganic fiber bundles including opening a plurality of the tough inorganic fiber bundles such that tough inorganic fibers can be dispersed in a liquid slurry to lay down a homogenous fiber aggregate, wherein the tough inorganic fibers have a crush settle volume of greater than 250 ml, optionally greater than 450 ml. Also, a method of treating tough inorganic fiber bundles including dispersing a plurality of the tough inorganic fiber bundles in a slurry with a dilution of about 0.1% to about 2%, optionally about 0.1% to about 1%, effective to lay down a homogenous fiber aggregate, wherein the tough inorganic fibers have a crush settle volume of greater than 250 ml, optionally greater than 450 ml.
