摘要

The present invention relates to a ceramic composite material having a high thermal conductivity. The ceramic composite material consists of a network of metal fibers embedded in a ceramic material and where the network of fibers on one side of the ceramic composite material extends out to the surface of ceramic composite material. A part of the metal fibers may be substituted by ceramic fibers and/or carbon fibers. Preferably, the area of the network of metal fibers occupies 60-95% of the total area of the surface wherein the network of metal fibers extends out to the surface of the ceramic composite material. The present invention further relates to a refractory lining for metallurgical smelting furnace wherein at least a part of the above described ceramic composite material is connected by a metallic bond to a cooled metallic part of the smelting furnace.
