ABSTRACT:
A monolithic refractory material is provided by a method including the steps of kneading cordierite powder having a median diameter in a range of 10 to 50 μm, and having a sharp mountain-like particle size distribution in which the content of particles smaller than 10 μm is 1% or more to 36% or less, the content of particles ranging from 10 μm or more to 50 μm or less is 50% or more to 75% or less, and the content of particles of 51 μm or more is 1% or more to 14% or less, and a solvent including water and alumina sol or silica sol solution.
