ABSTRACT:
A ceramic fiber felt is obtained by mixing alumina crystalline ceramic fibers having at least about 60 weight percent of Al.sub.2 O.sub.3, the rest being SiO.sub.2 and impurities, and having a filament length ranging from 10 to 30 mm with aluminosilicate non-crystalline ceramic fiber having from about 40 to 70 weight percent of Al.sub.2 O.sub.3, the rest being primarily SiO.sub.2, impurities, and, optionally, including a small amount of metal oxides, and having a filament length ranging from 5 to 30 mm, the weight proportions of the alumina crystalline ceramic fibers to the aluminosilicate non-crystalline ceramic fiber being from about 4:6 to 7.5:2.5, and preferably from about 4:6 to 5:5, and binding the mixture of components with an organic binder.
The ceramic fiber felt having a linear percentage shrinkage at 1400.degree. C. of only about 2% is very inexpensive compared to alumina ceramic fiber and is highly suited for use as or in furnace linings.
