Beschreibung
Zusammenfassung:	An electrical resistance furnace, especially for the production of silicon carbide, in which the furnace has a porous bed on its floor, and a gas flow is provided for withdrawing gaseous reaction products from the furnace. Alternatively, or in addition to the porous bed, a covering sheet is provided over the burden. In addition, ducts may be provided within the furnace, beneath the cover and/or in communication with the porous bed, for the removal of gaseous products. The furnace may be of the open mound type, without side walls, in which case the cover may be a flexible cover that covers the top and sides of the burden.
