Copper is a typical thermal conductor: kcopper = 401 ( W / ( mK )) at 25 0C. Air is usually treated as thermal insulated: kair = 0.024 ( W / ( mK )) at 25 0C. The thermal conductivities of several common density ceramic material are list in the following Table. Research shows that the thermal conductivity of porous ceramics can be approximately
