Abstract
An inorganic ceramic paper includes inorganic ceramic fibers and an inorganic binder system of fibers consisting essentially of silica. The binder system initially includes organic materials as well as the silica fibers, however, the organic materials are burned out of the ceramic paper. The silica fibers remain and flow so as to maintain the structure and integrity of the ceramic paper and hold the ceramic fibers together. Such a ceramic paper is useful in a variety of applications and is particularly useful as a filter in the inflator unit of an automotive airbag.
