1316993 Treating atmosphere in bakers' ovens DANFOSS AS 18 June 1970 [3 July 1969] 29610/70 Heading A2A [Also in Divisions B1 and F4] Air is treated to convert impurities by passing the air over platinum applied as a coating to the surface of an electrically heated element, which element incorporates electrically conductive beta silicon carbide and possibly silicon oxynitride. The use of the silicon nitride enables elements having a large surface area to be used while keeping the temperature of the catalyst at 200-300‹C. The treatment may take place by placing the element in a bakers oven or by use of the element in an airconditioning installation.
