A far-infrared emitter of a high emissivity approximating a black body is prepared by subjecting a body made from a stainless steel of 10 - 35% by weight of chromium, 1.0 - 4.0% by weight of silicon and up to 3.0% by weight of manganese up to 0.5% by weight of titanium, niobium and zirconium and up to 0.3% by weight of a rare element such as yttrium, cerium, lanthanum, neodymium and the like, to a blasting treatment to roughen the surface followed by an oxidizing heat treatment at 900 to 1200 C to form an oxide film on the surface in the form of protrusions having a length of at least 5 mu m.

Title
Far-infrared emitter of high emissivity and corrosion resistance and method for the preparation thereof.
