  • Thermal conductivity of refractory bricks

    2017-7-10 · Such as 1000 degrees centigrade, the thermal conductivity of lightweight silica is only about 0.35W, recrystallized silicon carbide products is about 17.5W/(m℃), graphite can be up to 35W (m℃). In addition to temperature, the thermal conductivity of refractory material bricks is closely related to its chemical composition and structure. When refractory bricks are made of crystal, the properties of crystal have obvious influence on thermal conductivity.
