PURPOSE:To produce a fibrous cordierite porous heat-resistant substance having excellent thermal characteristics such as heat resistance, thermal impact resistance and a low thermal expansion, having high strength and high porosity, having a high baking temperature range in which the fibrous cordierite porous heat-resistant substance can be readily processed into a honeycomb state or a board state. CONSTITUTION:Heat-resistant inorganic fibers and inorganic powder comprising an alumina source, a silica source and a magnesia source are dispersed into water and mixed. The mixture is incorporated with an auxiliary of a calcia source, further dispersed and mixed. After the dispersion and mixing, the dispersion is mixed with a flocculant, flocculated, made into a paper state and heat- treated. |
