Heating elements made of silicon nitride are very suitable as radiation heaters. The almost black silicon nitride used for the heating elements is a long-wave infrared radiator with a maximum radiation emission (ε > 0.8) between 8 and 11 µm at 1 000 °C. Thus, a wide variety of materials can be heated effectively by radiation: Sheet metals to be selectively heated or held at temperature for subsequent re-forming processes, as well as plastics where the weld edges are to be melted for a subsequent sealing process. In addition, plastics can be selectively "glued", or sharp edges can be rounded or thermally deburred by radiant heat.
