     Thermal conductivity of ceramic blanket is low and featured with excellent thermal insulation efficiency at a high temperature zone.The thermal conductivity of ceramic blanket is only 15% of the refractory brick and 38% of the light clay brick at 1000℃. Thermal conductivity of ceramic blanket is closely related to its density, temperature, shot content and fiber diameter.

     1)The thermal conductivity of ceramic blanket reduces along with the increasing bulk density, whose changing scope is shrinking. And the thermal conductivity won't decrease any longer when bulk density exceeds a certain temperature and even there is a increasing tendency of the thermal conductivity. 

     2)At different temperatures, a minimum thermal conductivity has a corresponding bulk density.

     3)The minimum density is corresponding to the minimum thermal conductivity , which will increas as temperature rises.
