PROBLEM TO BE SOLVED: To obtain a heat-resistant material having not only dust-preventing properties but also thermal shock resistance and durability, and further to provide a production method thereof. SOLUTION: This heat-resistant material is obtained by forming a glass layer 3 consisting essentially of a glass material 5 so as to be kept in contact with a substrate 2 consisting essentially of an inorganic fiber-based material 4. The substrate 2 includes a glass material 5 as a binder, and the glass layer 3 includes an inorganic fiber-based material 4 as a reinforcing material. The glass material 5 in the substrate 2 is fused with the glass material 5 in the glass layer 3 in the process for carrying out the heating treatment to form the glass layer 3. Continuity and integrity in physical properties are imparted during the heat treatment. The heat-resistant material can have dusting from the surface of the substrate suppressed by the glass layer 3, relieved situation of the stress concentrated on a heterogeneous part of physical properties of the glass layer 3, suppressed crack formed in the glass layer 3, suppressed generation of the peeling phenomenon from the substrate 2, thermal shock resistance and durability. |
