Thermal conductivity measurements were made on many types of refractory brick including high‐alumina, fireclay, silica, chrome, magnesia, forsterite, SKD, silicon carbide, and insulating brick. These measurements, made with a modified ASTM C 201–47 apparatus, covered mean specimen temperatures of 200° to 2000°F.
Silicon carbide (SiC) has high thermal conductivity. Because of the high surface area of Duocel® foam, heat transfer to/from fluids flowing through the foam is greatly accelerated. Duocel® silicon carbide foam is also ideal for use with phase change materials (PCM) because of the large amount of surface area, which increases coupling to PCM.
