  • Thermal conductivity of refractory bricks

    At normal temperature, the thermal conductivity of various refractory bricks can be from a few percent to several tens (w/(m℃), which is nearly a thousand times lowst than the highest value. As the temperature rises, although the difference between the thermal conductivity of various refractory bricks tends to decrease, but the difference is still large.
