ABSTRACT:
To provide a catalyst carrier holding material which is particularly useful for catalytic converters, by exhibiting heat resistance and high compression resistance in high temperature ranges, as well as excellent wind erosion resistance. The catalyst carrier holding material comprises inorganic fibers comprising alumina and silica, and the mullite ratio of the inorganic fibers is in the range of greater than 30% and less than 75%, and preferably in the range of 35% to 70%.
