PROBLEM TO BE SOLVED: To provide a heat radiation material having high emissivity of 0.9 or higher, bearable to a high temperature of 700°C-1,500°C, having sufficiently low cost, and enabling coating of an iron plate surface therewith.SOLUTION: A heat radiation material containing a composition formed by mixing an iron manganese oxide with silica as a base material, and formed by adding water as a solvent is described as follows: (1) a heat radiation material containing as a base material, a composition formed by mixing furthermore, at least, a small amount of silicon carbide, iron oxide and aluminium oxide, or (2) further, a heat radiation material in which the weight ratio of the iron manganese oxide to the silica is approximately 3:2, or (3) furthermore, a heat radiation material to which an inorganic adhesive is added. |
