Thermal conductivity: group 4
The thermal conductivity, λ, is the quantity of heat transmitted, due to unit temperature gradient, in unit time under steady conditions in a direction normal to a surface of unit area, when the heat transfer is dependent only on the temperature gradient [Ref. 2].
W m-1 K-1
Values are given at 25&176;C. To convert to W cm-1 K-1, divide by 100.
Values are temperature dependent. Thermal conductivity tends to fall with decreasing purity.
