CATALYST CARRIER HOLDING MATERIAL AND CATALYTIC CONVERTER

摘要

PROBLEM TO BE SOLVED: To provide a catalyst carrier holding material to be used especially for a catalytic converter provided with heat resistance, high surface pressure holding property in a high temperature region and excellent wind corrosion resistance. SOLUTION: This catalytic carrier holding material is made of inorganic fiber including alumina and silica. The catalytic carrier holding material is made so that a mullite converting rate of inorganic fiber may be in the range of 35 to 70%.
